If you are having problems getting Vertex to run on your system, please
read below:

FILE ERRORS:
  
    I've heard some people are having problems with some
    Lightwave files crashing the machine. Of the 20 or so
    Lightwave files I have, they all load fine. If someone could
    send me one of these files, I'm sure I can fix the problem,
    but I can't fix what ain't broken!


2.0 COMPATABILITY:

    I've heard someone has a problem running on 2.04. I've run the
    program myself on 2.04 with no problems, but I do know that just
    2.0 (not the 2.04 update) does not like Vertex. If you press the
    right mouse button and a pop-up menu appears, then the machine
    crashes, this is probably the 2.0 problem. As a solution, you can
    run in 1.3, but as far as I know the program works in 2.04. If
    anyone has experiences to the contrary, please let me know.


WIERD FUNCTION RESULTS:

    If you are useing lightwave objects, it's best to do a "delete
    duplicate edges" after loading, to help clean up the object. Sometimes
    there are extraneous edges created during the conversion process.
    Check the Euler number on the info panel (in white marked EULR:) - if
    the absolute value of this number is high, it's a good chance you have
    some duplicate edges in your object.
    
    If the new planar fill routine is not filling your object correctly,
    or if you get edges leading to the upper left and connected to
    nothing, then try these steps:
    
        1.  Try filling smaller parts of you shape which are not as
            complicated.
        2.  If you do this, then you should ensure your shape is
            continuous - that is, all the vertices are connected to 2
            other vertices, and there are no holes in the outile you are
            trying to fill. This can usually be accomplished by adding
            1 or 2 edges at the ends. 

    If bevels don't seem to be working, make sure your original shape has
    faces in it, and try flushing out the duplicate edges and faces
    by deleting them using the Delete menu options. Also, this
    function will only bevel a flat shape by extruding it. It will
    not bevel an already extruded shape. A quick fix would be to
    delete half the object from the side view, or just attempt a
    bevel on the front or back half of the object (as seen from the
    FRONT view)


USING THE MENUS:

    Since about half the people who have tried Vertex have expressed an
    extreme dislike for the pop-up menus, I thought I'd go through their
    operation one more time.
    
    Pressing the right mouse button anywhere on the screen will cause a
    pop-up menu to appear. You do not have to hold the right mouse button
    down - a menu will disappear when you move the mouse pointer off of
    it.
    
    Make selections by clicking with the left mouse button on your choice.
    For most menus, this will cause another pop-up menu to appear. Again,
    there is no need to hold any buttons down, moving off the menu will
    make it go away.
    
    I would strongly suggest getting a handle on the FastKeys. When I
    want to select vertices, I don't mess with the menu. I just type an S
    then an R. Now I have the pick pointer, and I can immediately start
    selecting vertices.

    Version 1.36.1 and above offer the traditional pull down menus.
    People who like and use the pop-up menus can go on using the
    software the same way.


INIT ERRORS:

    Error 73 is is a sure fire sign you're low on memory.
    
    Error 8 is an internal error. No-one should be seeing this error any
    more. If you are, please let me know as soon as possible.


RUN TIME ERRORS:

    Error 0 is a division by 0 error. I've tried to detect these be-
    fore they happen. 

    I have tried to make many of the functions "stable" by first checking
    to see if there is enough memory available. It is kind of difficult
    for me to fully test these types of things, since I only have a 2 meg
    machine. Be leary of error 8, which is the out of internal memory
    error. When this happens, you are trying to operate on too many
    vertices at once. Let me know when you run into this error, and I
    should ba able to alter the code a bit to fit any special
    circumstance.


    UNKNOWN RUN TIME ERRORS:

        Please let me know when you run into these errors. Include a brief
        description of your system set-up, and what you did before the
        error occured.

        If the UNKNOWN ERROR requestor will not go away, you may
        have to re-boot the machine. When errors occur, the system
        will abort any function and try to re-draw the screen. If the
        error occurred during a screen re-draw, then an infinite loop
        of errors will continuously appear. This should no longer
        happen, unless you have objects of extreme size (say millions
        of units in size.)
