1  Java Game APIs & Engines / JOGL Development / Re: How to: Getting started with JOGL on: 2007-02-12 13:29:27
Hi.

Can anyone say why my app(one of the lastest jogl and jdk6, WinXP SP2)  has these problems?
 
1. After going fullscreen the bottom part of the screen(START button line) is under the "start" button.
2. Before pressing alt-tab it draws a twice slimer line at the top of the screen, but after alt-tab this problem and the first problem  will be solved.
