mouse3 click, instant turn

[simc]

Hello,
A small thing, but every time after running GZDoom and starting a new game (or warping directly to some map) the first mouse3 button click makes the player instantly turn some 45-90 degrees to the right.

This happens only once per game session. If I click the button during the menu screens nothing unusual will happen in the game. If I record this happening to a zdo demo file, it'll be playbacked as a very very fast turn but in the real time game it's an instant turn.

This doesn't occure in ZDoom but only in GZDoom. It doesn't matter if I delete the config file or if any action is configured to mouse-3 or not. This happens on three different computers (XP, Vista) all having the basic two buttons + one mouse wheel-button mouse (Logitech, Microsoft). Mouse3 is the mouse wheel button.

I remember seeing this same happen with some other OpenGL sourceport many years ago.

I can't seem to replicate this on my system.

Then it's clearly a driver issue.
