the idea is that ctrl+f9 (in the main menu) turns on debugging globally and ctrl+shift+f9 (in the patch menu) turns it on in the active patch only and we have it a third time (in the edit menu) which allows you to turn on debugging only for selected nodes. the last two are the same: no nodes selected → patch.
anyway i removed it from the editmenu (think it does not need 3 mentions) and also moved the ExceptionDialog to the mainmenu (from edit). tanks fo da pointer.
