Hello,
I put this message under the "SfForm" - Control group because selection of "XPMenu" or "BarItem" is not possible.
When I click on a menu item (XPMEnus.BarItem), I get a message box from Windows that says "Bad IL Range", and the event handler is not executed. The most probable cause is that there is a call to an 32-bit assembly from my program.
Interestingly, this happens only on my laptop, which I have installed a brand new copy of Win 10 x64. It does not happen on my development machine, which has the same Win 10 x64.
What is going on here?
