Clip Browser 2.05.00 (Mac)
OS X 10.5.8

'Application quit unexpectedly' before anything was displayed. Anyone seen this or, better still, found the fix?

I believe the current version of ClipBrowser is 2.05.01 so try updating and see if the bug fix fixes this issue.
After doing that I'd repair disk permissions and then remove the ClipBrowser .plist (preference) file.
Next I'd create a new user with Admin status and see if it works there. That'll let you know if it's a user vs system issue.

Thanks Craig - I'll get the latest version. Some experimenting I have been doing suggests there may be a conflict between an IPod Shuffle which was connected and Clip Browser. Strange!
