JUANCAB  New version 0.9 released recently fixes login issues. Yeah!  
(Version 0.8)

JUANCAB  I used this widget for quite a long time, but suddenly it has now insisted I have the wrong credentials and never lets me log in. Purging the Keychain, widget preferences, etc. doesn't seem to have helps (neither has updating). Any ideas?  
(Version 0.8)

JUANCAB  Thanks for the recommendation for photorec, the command line tool that does everything PhotoRescue does. PhotoRescue has a nicer GUI and is 'easier' to use, but the truth is the command line interface for photorec is menu driven and simple and it recovered all the lost images from my Nikon D90 card without any issues. So if you are not afraid of command line, go with the free solution, use photorec.  
(Version 3.1.12.12057)

JUANCAB  Frankly, I can't say much about Gsync except that it fails on my computer to properly sync with GCal's address book. It's fairly useless to be because it doesn't work. That said, its a good idea and I hope the developer works to improve it so that it in fact works.  
(Version 1.0)

JUANCAB  The most recent version (0.6.5) crshes on launch under MacOS 10.5.3. I can't address any earlier version of MailUnreadStatusBar, but the current version doesn't even launch.  
(Version 0.6.5)

JUANCAB  Don't bother downloading it if you use Leopard, for some reason both the PPC and Intel Leopard disk images appear to be corrupted.
