Well 64 bit machines have been running the x64 version pretty well. 3D modeling software does use quite a chunk. Blender? Or do you have enough money to buy something else?
Anyway, Eon started as my attempt to help out people with 64 bit whose computers don't run Java very well. It's turned into my primary one because there's just so much more I can do with it. I didn't entirely understand your reply though, do you have the x64 version of the timer?
Odd. Are you using a 64 bit machine? I've heard of this happening a lot with those and the 64-bit version generally clears that up. Also, do you have version 1.11? I changed it so you could select the sounds and it seems to run a little smoother with some other ones.
