swing application consumes much memory

My swing application consumes the memory size of 50MB initially but If I open a new window the memory gets raised.
If I closed that particular window which I have opened, the application doesn't released the memory.

can you help me with this problem?
thanks

50mb of memory?
Wow that's a lot, for my computer spec that is, the largest program i ever use (excluding games that is) only reach 20 or 30
What kinda application are u working actually?

Memory release got some problem with garbage collector right?
I haven't really understand that part, but maybe u should call the garbage collector explicitly instead of waiting for it to move on its initiative maybe?
From what i read just yesterday, in JavaTips there if im not mistaken, garbage collector sometimes make the application a little slower cause it came at inproper times, maybe u should find some more info bout it
And check ur default close operation also, just in case u miss some bugs or something, wouln't hurt to double check
Sorry couldn't help too much :(
