I decided to reinstall my Windows 7 because the install was showing it's age (2015). I reinstalled Blender 2.49b (for Fallout New Vegas meshes) and now have the problem that whenever I turn my camera by clicking the middle mouse button, the skeleton moves "out of the armature" like this:
It "snaps back" after I release the middle button and e.g. scroll around to zoom in and out. It is highly irritating and I have no idea whether it will also affect exports. I tried reinstalling video drivers but everything is up to date as far as I know. I even reinstalled Windows 7 again to no avail. Did anyone else encounter this issue and possibly knows a fix?
EDIT: Sorry, I'm apparently too dumb to have the images show here and it also removes my greetings.
