A couple of minutes ago, while playing, I began experiencing a strange issue: whenever I keep pressed for a second or more some of the keys, a pop-up appears asking me to choose from a set of similar characters.
Some considerations regarding this issue:
- I never ever encountered it before today.
- I installed Diablo 3 on day one, and never had any issue with it (~30 hours of gameplay to date).
- The problem began in the middle of a gaming session, an hour and an half from the start.
- I didn't install anything or changed any setting, neither in the game nor in OS X.
- The pop-up seems belonging to OS X, because of its look and the fact that it can't be screenshotted neither by the game nor the operating system.
- I could not find any setting that could be related to this in "Keyboard" or "Universal access" in "System preferences".
- I don't know if I hit some voodoo key combo while playing.
- I already tried the classical help desk solutions (close and reopen the game, restart the computer, etc) to no avail.
- It does not happen with other applications (e.g. Firefox, Terminal).
