Right click causes context menus to be 'moved'

[gms8994]

I'm on desktop 1, and a right click, within any application, causes the context menu to flash, and then disappear, appearing instead on desktop 2. It just started doing this a few weeks ago, and took me several days to figure out what the problem was.

Is there anything I should look for in the configuration to make this stop?

Usually, behavior like this is caused by a desktop rule (with action 'move to Desktop 2') whose conditions are so unspecific that it matches every context menu. Disable your rules one by one to find out which one is responsible.
