I have a sheet of images 40 x 40 pixels.
Using these as sprite images, I can set current frame to any value up to 100
After that, it doesn't work.
Is this a genuine limit?
If so , any ideas about how to exceed it?
I have up to 600 static sprites on screen (using very like a tile map) and there are 455 possible states.

Meh.
Fixed it.
I still has some of the sample code in the project, which had a hard coded limit of 100.
Do'h!
