Browser: FF 4.0.1
OS: Mac OS X 10.6.7
Any context enabled component (grid, tree) doesn't hide the context menu if no selection was made.
Steps to reproduce:
1. Right click on a context menu enabled component
2. Don't select any menu in the context menu
3. Clicking anywhere in anywhere other than the context menu won't close/hide it
