I am having the same problem since I upgraded to 9310. I am running Windows 7 ultimate.
It bothers me a lot...
I-che's suggestion to disable Autohide in Windows Taskbar seems to work for me.
However, after disabling Autohide, any Windows application window cannot stretch all the way down to the bottom of your screen. It can only go as far as above the (ghost) taskbar. This still bothers me.
Quick solution from Parallels is to be expected.
