Date: Wed, 29 Mar 2006 17:26:55 +0200 CEST From: "Fran���is Revol" Subject: [SDL] BeOS port fix: PrintScreen key crashing It seems the latest SDL crashes when someone hits the PrtScrn key in ZETA (BeOS R6), somewhere it gets a negative value as key code (or a big unsigned maybe ?), and uses it as an index in the keysym table... I'll investigate the cause for the negative value, but it's always better to check for bounds correctly when indexing a table. The attached diff fixes it.
