Hi,
We have had a few reports of people having trouble with ITunes and ObjectDock Plus. However we have not been able to replicate the troubles people have had with regularity of any kind. If you are having troubles with this please post here and let me know. Please be sure to include your OS.
Just before you post a few simple things corrected the issues for a few people.
-update video drivers (even more important with NVidia Vista users)
-update to latest versions of both peices of software.
Should you be having troubles in just this kind of conflict please let me know here or start a ticket with support@stardock.com.
Cheers
