a)only seems to happen if there's another polyobject that's mirroring it
b)only seems to happen to north and south sliding polyobjects
c)speed values below 10 seem far less likely to have any problems.
d)speed values that are multiples of 10 don't seem to have these problems
e)polybjects that have to move further (say a value of 255) will *slightly* lessen your chances of having a problem (not by much though).
I've set up an example wad to show this:
The first door shows this problem, and will scroll indefinitely.
The second door works normally.
The third door shows this problem, and will scroll indefinitely.
The fourth door works normally.
Also of note, is that swinging doors seem to have problems as well. Whether it's related to this or not, I don't know; haven't had a chance to take a look at it yet.
If you want a example of it, load up this:

And in the console type "warp 4300 -95" and use the door in front of you. It will swing around twice before coming to it's proper position. In older versions it did not do this.
Once again I'm sure this is related to zDoom 2.0.98, but I've only had time to thoroughly test this in GZDoom; and besides, you'll probably find the problem and fix it before Randy will anyway.
