Masive patcher with memory leak. Anybody hire out for revieweing patchers?

Josh,

Maybe I am not understanding the nature of the problem. I understand that the jit.gl.text2d object is memory intensive, that should just effect performance. The issue I am running into is that the jit.gl.text2d objects consume more and more memory as the program runs,even if it is never closed and reopened. Given that I have defined a preset array of text2ds, shouldn't the memory hold steady (none are being created or destroyed just having their attributes changed)? If my code above is inherently leaky could you point out where so I can understand the concept better? I have been reading up on javascript and thought I understood how gc worked.

I have reworked the patch so it only has three text2d objects using the suggestions you made in the other thread. It is running as a standalone now on a test machine. So far it is looking good, though it is very processor intensive to render scrolling text this way. he big plus is that when nothing is moving nothing is being rendered. Thanks for all your help with this, it is very much appreciated.

For those searching from scrolling text2d the code I ended up with is below (it is messy since I haven't had a chance to go back and clean it up. There is a matrix in the patch called "werds2" which feeds to a jit.window. I'll come back and post a simplified patch when I get a chance.
