Indesign - main navigation menu glitch
When I hover my mouse over any of the main nav items (file or edit or layout etc.). and click the menu does not appear. When I click a second time it appears but does not allow me to browse down to select any items - them menu items disappear as soon as I move my mouse. This happens on tool menu items too such as the links window menu. It doesn't do it all the time, but say 1 in 4 times I open indesign. Super frustrating - any one else have this bug/ issue?
