I'm running Tiger 11 on a Mac Pro, and had an earlier version of Quicksilver - I think it was build 3815 - working succesfully and without problems, using the default activation hotkey Ctrl-Space.
Recently I got a new app called Mathematica 7 that needs that hotkey combo. So I used the QS Prefs to make QS' activation work from Cmd- Space instead, as I'd seen suggested elsewhere. This didn't solve the problem because while Cmd-Space did activate QS, so did Ctrl-Space. IOW QS didn't release the Ctrl-Space hotkey. So I downloaded the latest version of QS, beta56a7, and installed it over the old one by replacing the old files. Now I can start QS, but anytime I try to activate it by any method, it immediately crashes. In fact after a few minutes it crashes anyway, even without trying to activate it. The crash log each time has the lines Exception: EXC_BAD_ACCESS (0x0001) Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000034 except the last two digits '34' may be something else, such as '28'. What is the recommended way to get past this difficulty? Thanks. - Dushan
