I've had this happen too often now for it not to be a
bug. I have not reported it before since I have nothing
to offer in way of a crash dump or model to help figure
it out. But here goes.

I have had Wings lock up on me tighter than a drum
where there is nothing I can do except the dreaded
Ctrl-Alt-Del routine. This happens when I am examining
a model via the Middle Mouse Button, twirling it around
in a series of short back and forth movements. While
twirling, Wings suddenly locks up, to where I can do
nothing with it. I have to do a Ctrl-Alt-Del. Then the
task manager comes up and says

Wings3D – shield.wings (not responding)

The mouse still won't move, so I have to do an Alt-E
(end task) and another Alt-E to actually do the deed.
Poof to Wings, and all my work is lost. I ran into this
a lot doing Bag End, and got in the habit of doing
frequent saves. But tonight I was working on a small
model, a shield with only three parts, and it did it
again. But since I can't save the model, and it does
not generate a crash_dump, I don't know how you can
work on this. But since it results in a catastrophic
loss of data, it really needs to be addressed. I can
send you the model, if you think it would do any good.
But just create a model, extract a few parts (my model
had three objects in it; shield, strap, handle – they
had each been smoothed once).

    Here is a very close approximation of the shield model as it
    was when Wings locked up. Try and see if you can duplicate
    the lock up by MMB movements.

    I don't think this problem is dependent on the model being
    used.

    This problem is not in Wings itself, but in something called
    SDL (a C library intended for writing cross-platform
    multi-media applications). A long-term solution that we are
    considering is replace SDL with our own library more
    suitable for Wings.

    In the meantime, I might do some changes in the way Wings
    handles the mouse cursor in camera moves. I have a few ideas
    that I might implement as preferences so that you and others
    could see if it makes things behave better.

    Do you run Wings maximized or in a smaller window? Does the
    probably occur if the Wings window is maximized?

    Yes, I almost always use Wings maximized except when I'm
    working on the UM. Not sure it it has ever happened
    non-maximized or not, but will watch for that too. This was
    on my home Win98 PC. Not sure if it's happened on my NT PC
    or not. If you do your own libraries, would that fix the NT
    refresh problem too?

    Did I understand you correctly (from a post in the forum),
    that a recent release of Wings resolved this problem?

    Unfortunately, no. Here is my last post in the Wings is
    Freezing Up thread at the forum.

    "I hate to say this, because I thought this bug had been
    squashed, but Wings froze up on me again today when I was
    modeling the interior of my space craft. :( This is the
    first lock up since 0.09.01 (or was it 02) came out. This
    happened after I had been modeling for quite some time, so
    perhaps it has some dependancy on the number of operations
    performed prior to lock up? All my other tests have been on
    fairly fresh models where I had done just a few things
    before trying to exercise the mouse to cause a lock up. One
    other point that may help track it down (I hope) is that by
    killing any other process in the Windows Task Manager (this
    time I killed AIM) Wings gets unlocked and then I can save
    my model."

    It is much less likely now, but I can't say that it has been
    eliminated. And it does seem to only happen after lots of
    modeling activity. And I have quit working with Wings
    maximized, if that matters.
