Labview Control and Function menu's stopped working.

[pspring]

Most of the menus no longer work. The top level menu will pop up with a right click but the submenu's do not. I cannot get to the submenu which contains a While Loop for example. If I use the stickpin feature then I can navigate the menu's fine.
Labviews main menu does not entirely work anymore also. Tools and Browse are nonfunctional. Sometimes if I restart labview the Tools menu will respond the first time I select it but after that it no longer shows the submenu when I click it.
Very unusual. Thanks in advance for any help.

Also, if i right click on a boolean control, the Visible Items submenu does not show. The only thing that works it the "Replace" submenu.
PS. The Front Panel right click popup menu seems to work fine. Its the Diagram right click submenu I am having the most trouble with. 🙂

I figured it out. The only changes I had made to my system was some video card drivers. I have 2 monitors and use Win2k Pro.

I had selected an option to automagically center all popup windows. That was the problem. It was messing with labview whenever a menu/popup was attempted to be shown. Submenus in Labview must be considered or tagged as popups to the operating system. I disabled the "feature" and now everything is back to normal.
