I've upgraded to 10.5 and every once in a while, FastScripts just stops responding to keypresses.
The menu still works fine, but no matter what app-specific or global keyboard shortcuts I try, nothing triggers. Until I go to the menu with my mouse and click. Or restart FastScripts.
It just happened again. I see nothing in the console when I press a (now) non-functional FastScripts key combination. And there's nothing FastScripts-related in the console, in case it logged an error when whatever went wrong happened. At least, nothing that's obvious.
Hmph. I'm at a loss for what to do here. Since I still haven't seen the behavior in 10.5 or 10.5.1, I am not sure how I can debug and find the root of the problem. I'm going to post a blog post about it, and maybe it will bring in some more data about whether it's happening to other people, and if so, if they have any ideas about what is prompting it.
Where a similar problem has been reported. And in chat with some developer friends a couple incidental "weird things" with keyboard shortcuts have been reported.
I'm suspicious that this might be an issue in OS X that only Apple can fix. I'm going to wait and see if I can gather some more evidence and then open a bug with Apple.
