i'm not sure if this is the right place to ask this question, i've had a quick search and i can't find anything that helps. but basically after upgrading to 6.40.5 pro from the 6.31 trial i've found that when the player model collides with models in the level (e.g. buildings) the screen jerks around a lot.

i'm not sure what's happened as all i did was build the same level i made with the trial. when i walked into a building in the trial version the player was stopped then smoothly slid along it's surface the more you pushed into it, but now it jerks around quite a bit.

i wonder if this is something anyone else has encountered? i may have neglected to update a specific file? i'm using the plBiped stuff from template_6.

anyway, hope someone can help!
