On my Windows only: I haven't noticed if it happened between 1.4.2 and 1.7.2, but ever since I've updated to 1.7.2, my mouse intermittently switches between barely responsive to hypersensitive when moving the point of view around. This problem does not occur when searching through the inventory or options menu, only while walking around. Just to point out, I do not accidentally hit the accelerating/decelerating button on my mouse.
Both on Windows and Mac: The next issue has to do with the doors. The doors' textures are sometimes mirrored. For instance, on one side, double doors have their handles in the middle, on the other side, the handles are on the outside of the doors.
One more issue that hasn't happened often would be that, on occasion, on Mac, there would be two soundtracks playing at the same time, and the interval is much shorter than it used to be, and it seems to get progressively shorter. Opposite to the Mac version, on Windows, the soundtracks almost never play.
The Windows is a Samsung R580 with Windows 7, and I use a Delux M555 USB mouse.
The Mac is an iMac9,1 with Snow Leopard.
I hope I'm not the only one getting these issues.
