Carl Mercier successfully answered Rich Collins's question:

I keep getting hang ups in the OS X UI when I am doing things like typing in a text field (especially in the Adium message text area). The hang ups (usually a second or so) seem to coincide with a spike in disk writes. This is getting really annoying when combined with my [other issue](http://guruza.com/question/122/reward-125.00). Any ideas?

Rich,

Also had this problem with Adium. Delete it and reinstall the lastest version. It did the trick for me. There was a bug in an older version. You might want to remove it with AppZapper to make sure all the files are properly removed.

It was the disk as you suspected.
