Working in LR I am repetedly seeing this issue where on selecting files to delete for instance, a box appears to confirm deletion but without the visible Yes or No. Likewise if I click on File or Edit from the menu bar, I can see an outline of the box but no content. Switching to a web browser, the context menu functionality is also lost. This issue only happens when LR is open, I do not get the issue just working with a browser.
Logging off my windows session and then logging back in restores the functionality until I start using LR again.
