I assume you mean MaxGUI. I just fixed a memory leak in fltkmaxgui, almost to be expected in fltk except that this wasn't fltk code. So there may be some leaks on win/mac too.
I would suggest you try to track it down by building sample apps and seeing which ones leak, it may be specific to a gadget.
