Platform: Windows 7
Problem description: When searching, pressing Alt+r (to toggle search regexes) if the menu bar is hidden brings up the menu, which is not supposed to happen. Strangely, the behaviour seems to be limited to Alt+r, since Alt+c (case sensitive) and Alt+w (whole word) work as intended. I can reproduce the problem using regular search, incremental search and Find in files.
Can anyone else duplicate this problem and/or does anyone know a solution?
