Fixed bug #619 Description From Tim Angus 2008-08-31 03:38:36 (-) [reply] When pressing "system keys" e.g. ALT+F4 etc., the default for the windib driver is to ignore them completely, whereas with the directx driver they're handled (badly as it turns out). As the windib driver is the default, I assume its behaviour is considered correct, so the following patch makes the directx driver the same in this regard.
