Background: I am logged on as an admin to OS 10.5.8 on a 1.83GHz original MacBook Pro with 1.5 gig RAM. Recently (can't associate with an update or anything else obvious), I have found myself able to unzip new widgets and add them to the system library/widgets folder. They appear properly in the 'manage widgets' strip at the bottom of the display. But when trying to open them, each crashes the dashboard. This is somewhat frustrating because the legacy widgets (clock, calculator,etc) and some new 3d party ones (iStat, Periodic Table, Easy Envelopes) are fine. The problem isn't specific to particular new widgets, either. I've tried removing every offending widget from both the system and user library folders, trashed the com.apple.dashboard.plist and com.apple.dashboard.client.plist files (which rewrite themselves properly on reboot), repaired permissions, am logged in as an admin, rebooted multiple times, zapped the PRAM, and have no accounts with parental controls running. Any suggestions?
