System:
iMac DV/400MHz Graphite SE
256 MB RAM
Mac OS 10.1.5
Screen resolution: 800x600

This is a friend's system who isn't having much luck with Aquarium running as a screensaver on his system. It works fine for a short period of time and then his iMac locks up. The time 'til the lockup occurs is highly variable, ranging from 17 minutes to approximately 45 minutes. When it locks up, the aquarium is onscreen, but not moving and no mouse clicks or keyboard clicks will exit making a forced restart necessary.

I had him set his energy saver prefs to never to eliminate any possibility of that timed sleep, hard drive sleep or dispaly sleep was causing a bad interaction. It still freezes even with energy saver disabled so this isn't the cause.

I've had him set the number of fish back to 3.. also with no effect... the iMac still froze.

Just out of curiosity, I had him disable the screen saver version and try the Marine Aquarium application. This appears to work without freezing up his iMac. He's had the application running in full screen mode for a couple hours without a problem, far longer than it ever took for the screen saver version to cause a freeze.

---> Any thoughts on what might be occuring that that would make it not work as a screen saver, but work fine as an application?

Also, for reference, with the iMac set to Millions of colors, the frame rate is only 14-15fps at 800x600. is that about all that can be expected? Set at thousands, it's approx 30fps.

Do you think this is a bug in the screensaver version related to the Graphics card in the iMac DV. I first thought it might be an overheating issue, but since the application works, I'd think that pretty much elimiates as a cause since I'd think everything is cranking away just as much to display the aquarium in full screen application mode.

Any thoughts or insight?
