ww web:
I've been using Picasa on Linux distro installs for ages now, have not had the prob you report, tho there have been times it has slowed it down, shortly after install while it is scouring the drive for images, as I do have quite a lot. I simply open up the process manager if I can't shut it off manually and force explorer.exe to shut off, then restart the app.
expl. exe lijkt bij het prog te horen...
