Issue Details

I'm using LabWindows/CVI or running a LabWindows/CVI program on a computer with multiple or high-resolution monitors. When I try to open a drop-down menu from the LabWindows/CVI toolbar, or a menu button/ring control on the program I am writing, the drop-down menu appears offset from the menu button, as shown below. How can I resolve this behavior?

Solution

This behavior is usually caused by fullscreen optimizations utilized by Windows on multi-monitor or high-resolution setups to improve program appearance and boost performance. On certain programs, such as LabWindows/CVI, it can cause menu disjointing and other graphical issues. These optimizations can be disabled for LabWindows/CVI through the following steps:
  • Navigate to the location where the CVI executable is installed on your computer. By default, this executable is installed at C:\Program Files (x86)\National Instruments\<Your CVI Version>\cvi.exe.
  • Right-click on cvi.exe and select Properties.
  • In the Properties dialog box, navigate to the Compatibility tab and select Disable Fullscreen Optimizations. Apply your changes.

After disabling fullscreen optimizations for LabWindows/CVI, you should no longer see the drop-down menu disjoint issue.
