Applications :: ITunes Relaunches Automatically - Compressor Not Launching

I'm running iTunes 7.6 on a MBP 2.4GHz with 10.5.2 installed. Last night, after having a problem with Compressor not launching(ie it would launch but no window would display), I was forced to take Apple's Compressor Troubleshooting basics and trash Compressor, Qmaster, and Motion. I reinstalled those applications without a hitch and everything is working. Or so it seems until this morning when I tried to play a song in iTunes. It would hang up briefly, then quit. The subsequent error message was that "...The Problem may have been caused by the FX plug-in." I trashed CoverSutra, thinking that may have been the problem, despite the fact I never used it. I even uninstalled iWOW2 with no results. Trashing the iTunes .plist did yield some positive results as songs would play, but if I tried to quit iTunes, it will automatically relaunch.

After perusing the Apple support discussion, it seems this is a common problem, although many of the reports were from last month. I just find it odd that all of a sudden I'm now encountering these problems. I do have Synergy installed, but I've never had any problems with it before in the past and even with it not running, iTunes still behaves poorly.
