jogl v2.0-rc11 happens when pressing Alt + most keys. happens NOT when pressing Alt + F1..F12. Alt + SPACE opens the system-menu, so i think this problem is caused because there is a sys-menu in fullscreen mode.
v2.0-rc11 is very old and a bug report against this version is invalid, especially regarding NEWT keyboard input processing - implementation has changed! Please test your use case against on of the latest aggregated build: http://jogamp.org/deployment/archive/master/?C=M;O=D BTW: The ALT key is probably mapped to some system functionality, and hence the erroneous behavior ?! If you can reproduce and the above constrain is _not_ the case, please reopen, thank you! In such case, it would be great if you can use one of our unit tests to reproduce the bug, or create a new one - and attach it to this bug report and/or offer a git-patch.
