Problems doing updates?

I’ve only recently been using your plugin, and I love it, but have run into a problem.

I can successfully install plugins via the WordPress interface and ssh2, but I can’t seem to run updates. I click “Proceed” on the updates page, and……. nothing happens.

It’s possible that this is a problem with our server configuration, and I’ve sent a ticket to my sysadmin, but does anyone have any ideas? I tried searching the forum for similar issues and didn’t see anything.
