I'm using a SuSE-Linux 10.2 with the standard JDK 1.5.0_10, running IDEA 6.0.5. In the last few hours IDEA sometimes suddenly disappeared when pressing CtrlAlt key combinations (e.g. CtrlAlt+L). First I thought, it might be a problem with with the windows manager (used Gnome before), but the problem also happens with KDE. Since I haven't had such problems on Windows (same machine), I believe, there could be a problem with the JDK.
Does other users also had similar problems?
