When I open the app. it won't load and a popup comes up saying "There was a java error that may prevent you from continuing." Then it says that this should help diagnose the problem: java.lang.OutOfMemoryError: Java heap space

What's that supposed to mean, and what am I supposed to do?


Please help T^T

what size canvas are you trying to draw on? how much memory does your computer have?

400x400 and my computer has 221.8GB free

hrm. 400x400 shouldn't cause any huge problems... there is a way to increase the allowed memory on Java, but I'm surprised that you would need to do that. couple of diagnostic questions: what operating system are you running, what version of java, and how much ram do you have (not hard disk space)?

Windows Vista, the Java version is 6.0.30.5, and I've got 3GB of RAM

Do you know if you are running Vista 32bit or 64bit?
Try messing with the java memory settings following this tutorial: http://www.duckware.com/pmvr/howtoincreaseappletmemory.html
the 300MB they suggest should be more than sufficient, but if you still get an error, try higher/lower.

the tutorial worked, thanks! ^.^
