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.
