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.
