I've recently joined the .Mac service and have tried using iDisk to share certain files. Trouble is, lately my internet connection has been a bit flakey, and it seems whenever my Mac is accessing my iDisk while the connection times out, it locks my computer. I've tried to relaunch the Finder, but that doesn't work. Is this normal, or is something else going on that I should look at? At this point, I can't really trust iDisk because of the risk of locking the computer. I'm also considering switching providers since they insist everything is normal. But that's another story.
