Division by zero in Display

[darkmoon]

Just found this problem when switching my game to the background, and back to foreground again...

java.lang.ArithmeticException: / by zero
   at org.lwjgl.opengl.Display.sync(Display.java:394)

Am I causing this? Is this a known problem? Can it be fixed or can I make a workaround?

It looks like you passed in 0 for the fps parameter for Display.sync() (as near as I can tell by looking at the source).
I still don't think it should crash. Maybe produce a useful error message or something.

Er, that is a useful error message... I meant the only alternative is some other RuntimeException anyway isn't it ("IllegalArgumentException") so what would be the point?

Indeed, that was it  Not intentional of course, it was caused by putting the app in the background during the short fps test...

Thats true. I guess it wouldn't gain anything. Nevermind, then
