Message:

VBoxTray/VBoxSeamless: Fix for the issue - A small rectangular bar appears over the start button for Vista and above in seamless mode when mouse is hovered over the start button..
Solution:
The start button size reported incorrectly by the OS. The rectangle has been cut to avoid the rectangular bar glitch.
