Good Afternoon, I hate to be the bearer of bad news but, this bug is also happening to me. I'm runnin Geany on a Win 7 64 bits laptop and every time I hit Ctrl+F it crashes with any error message...
I've attached : - a txt file with the debug messages prior to hitting Ctrl+F (the badly formatted email is only warning, shouldn't cause the crash) - a Capture Screen of the messages issued when loading the Find Dailog ( aparrently if complains about some fonts ???)..
hope it helps.
