[BMenu] have some issues

[diver]

*1. Open Find window in Tracker and press "All files and folders" menu, while it selected click on BTextControl - menu should close, but it won't.

*2. Repeat step 1 but click on BPanel and then click that menu again, menu should open (selected) but it doesn't happen. Another example: open Find window, click on desktop and then try to activate " All files and folders" menu, you will need for this 3 (three) clicks, and 2 under Be.

*3. While menu is opened Esc should close it as in BeOS.

*4. On menu activation blue border around BTextControl should disappear.
