Somewhere along the line, my Illustrator modifier keys (Shift to constrain to a square, option for smaller intervals, that sort of thing) just stopped working. Apparently this isn't a new or surprising issue, but I can't seem to find a fix that actually works for me. Ideas that didn't work include:
- Turning off secure keyboard entry in Terminal.
- Quitting a version of Office that I don't even have.
- Quitting all processes of a "scheduler" type. I went ahead and quit them all, except system ones. Missing Sync listener, Quicksilver, etc etc.
- Standing on my head and praying to Zeus to bring back normal functionality.
