------- Additional Comments From mikolaj.zalewski@gmail.com 2006-30-06 13:02 ------- The reason of the crash is the NM_TOOLTIPSCREATED notification sent when the application is not prepared for it (the ScintillaEditView::execute is called with this==NULL. This exception is caught in WinMain which tries to show a message box but that generates a WM_ACTIVATEAPP which crashes in Notepad_plus::checkModifiedDocument as _pEditView is uninitialized - this is the crash we observe). If I comment out line 5649 of toolbar.c Notepad++ starts but I haven't investigated what's the correct behaviour.
