When waking my MBP from sleep mode, I noticed that the cursor would often be extremely slow and jumpy, to the point that it was nearly unusable. A reboot was the only way to fix it. This thread on the Apple forums hinted that iStat Pro, the popular performance statistics widget for OS X, may have been causing the problem.
I disabled iStat Pro and had no problems for weeks. Problem solved.
On a lark, I re-enabled iStat Pro yesterday, and sure enough, the problem returned. While this isn’t a scientific test, it’s as close as I’m going to get to solid evidence that iStat Pro is causing the slow cursor problem on Leopard.
Update 5/10/08: After a giving the iStat Pro gurus a few months to fix this, I decided to try again. I’ve been running the latest version of iStat Pro for a few weeks, and this problem appears to be gone.
