I updated to 3.0 and tried to run some auto-updates for themes/plugins, but it seems to hang forever and never finish updating (or possibly it is just taking a looonnnnnggggg time).
I took a peek at what was going on in my FTP listing and it looks like it created a file in the "wp-content" folder with the name of one of the things it's updating, but even after some time it is still 0 bytes in size (according to my FTP app).
I tried canceling the update, deleting the temp file and the .maintenance file, then CHMODding the entire "wp-content" folder recursively to 777, but it didn't seem to have any effect.
Anything I can do to fix this? Thanks!
