I am having issues with WB and the right-click menu in IE7 only. The right-click menus seem to be fine everywhere else other than IE7. Here is how mine looks like in IE7:

At first I thought it was a skin issue, but seems to happen with all skins. Here is the system information from my WB:
WindowBlinds version : WindowBlinds 5 (5.5 (build 92 x86))
WindowBlinds is installed correctly on this PC
WindowBlinds appears to be activated on this PC
Your machine supports per pixel borders on WindowBlinds skins.
