As I've reported in the past, my mouse frequently gets stuck to the side or top of the screen in X for some unknown reason, and either doesn't move except along the edge, or moves and snaps back with any sudden motion. I've attributed it to problems with restoring floating point registers from signal return, so when it happened last (about 5 minutes ago) I decided to attach gdb to it to check the values of the FPRs. Examination came up with nothing useful, so I detached and went to restart X. However, upon detaching, I found that the mouse cursor has been restored to working order, so no X restart was necessary. This is somewhat confusing, I didn't expect gdb to modify the state of the running process at all, but maybe someone else can shed some light on this. - Justin
