Notepad++ crashes under all, but this particular situation when a document is open in npp+ (Notepad++). To test this use gedit to alter a .txt when npp+ has the same .txt open as well.
To avoid this crash, configure the following;
1. Make the check box "Enable" checked in "File Status Auto-detection" (the box of options) within "MISC." (the tab) within "Preferences" from "Settings" (the menu's option).
i.e. have "Settings" -> "Preferences" -> "File Status Auto-detection" -> "MISC." -> "Enable" checked
If you activate a toggled menubar (Settings->Preferences->Menu Bar->check box "Hide (use Alt or F-10 key to toggle"), then close the Preferences window, you will not have a menubar. There are two known options to regain the menubar. (Bug 21918)
Option 1 - disallow the window manager to decorate the windows
Graphics->Window Settings->uncheck box "Allow the window manager to decorate the windows"
Option 2 - have Wine emulate a virtual desktop
Graphics->Window Settings->check box "Emulate a virtual desktop"
Both options are configurations to Wine which can be found in "Wine
configuration", which does not need to be started from the command-line;
that is just the method that I've chosen.
