When I select a menu item and then release the left mouse button I’m getting an OnLButtonUp() sent to the window which is under the mouse cursor. It happens on the main menu as well as popup context menus. This is causing me problems as the underlying window is a tree control and the selection is changing.

I’ve checked a previous build of my app which used Prof-UIS 2.50 and this problem didn’t exist. I’m now using Prof-UIS V2.62

Here is a stack trace:

How can I stop these OnLButtonUp() calls?
