We can reproduce a small problem with context menus with several versions of VFP after we use the lateral scroll of the mouse.

STEPS TO REPRODUCE
1. Modify Command in the command window (any prg, even a new one)
2. Click the scroll button of the mouse and move the mouse to the right (left makes it too)
3. Right click somewhere on the same window to open a context menu
4. Left click on the window again
5. Now, the contect menu is locked and left open. Only a few methods allow to regain control of the app (For exemple, left click on the main VFP title bar).

This behavior happens on many windows and controls (editor, grids, edit boxes, textoxes, etc.), for VFP context menus and also for our context menus (in our apps). By luck, the lateral scroll is not widely used, but for the clients accustomed to it, the locked menu is very ennoying.

Has anyone a fix for this problem?
