Mouse problem on MacBook

My thread on the Mac Users forum did not come up with a solution, nor did the first few exchanges with tech support, so I'm going to ask here. (Nevertheless, many thanks to CuppaManga and the tech support folks.) I'm still hopeful for tech support, but we'll see who comes up with an answer first.

I hadn't played for a few weeks; when I logged back on and applied the March 2 patch (which may or may not be relevant) my mouse started acting strange. A single click (press and release) registers as a press but not a release. I have to double-click for the game to register both; otherwise it thinks I am clicking and dragging. Furthermore, moving the camera ("mouselook"), which I have tied to the right mouse button, usually only registers for half a second, after which it stays in that mode with the cursor invisible but no longer moves the camera. Sometimes it never moves at all, and more rarely it works fine until I turn it off, but never twice in a row.

These results are on my MacBook; they apply the same on the built-in trackpad and on my USB Logitech TrackMan Wheel, and in both full-screen and windowed mode.

Has anyone seen something like this before? Does anyone have any suggestions that might fix or diagnose it? Thanks much.

After reinstalling the driver for my Logitech mouse, everything works fine. Move along, nothing to see here!
