I recently bought a used Win 11 box. I set up Windows Subsystem for Linux, installed Ubuntu, & installed LO. When working w/ forms, right clicking on controls at the bottom of the form window results in a context menu w/ the lower half cut off where it meets the Windows task bar. I want to select “Enter Group” & “Arrange: Send to back”, both of which are in the bottom half. Is there any way to move the context menu up? Or access the lower half of the menu by other means?

To be clear, I have LO installed under Windows, & I’m using the Ubuntu installation to check for problems that come up when my app runs under other OSs. If I see a problem with the visual display under a particular OS, it’s a lot easier to correct the problem in that OS than to go back & forth between two OSs until the problem is corrected, which is what I will have to do if I can’t access the entire context menu under Ubuntu.
