The last few versions of WB are conflicting with the NOD32 Antivirus interface.
NOD32's main window is a tree view. When you click on a tree item, a new window pops up with the information/settings for that tree node. With WB loaded, when NOD32 runs, all of the tree node pop up windows show up stacked on top of each other and they cannot be closed.
I have confirmed that it is WB that is causing the issue. Without WB loaded, NOD32's interface behaves as it should.
