--- Comment #49 from gat gatlinsullivan@yahoo.com --- Bernhard, I thank you for testing. I was too exhilarated to believe that this was just randomly fixed without anyone pursuing it.
Since the current version of wine staging (1.9.5) produces the usual failure (non-virtual desktop crash) in all save the newest (6.9) version of Notepad++, then I can't do much to indicate that it is resolved nor exclude 6.9. The way that the AppDB has Notepad++ set is that 6.x is one series and since only one derivative in that series works it doesn't make sense to me to break 6.9 into its own version.
Maybe someone with the authority to re-title this bug entry to "Notepad++ versions prior to 6.9 freeze if native application changes a file it has open when not in a virtual desktop (dogfood)".
