Thanks for the update. Converter worked. Will see if I can find the memory leak. Although from what I saw from the profiler yesterday morning, not 100% sure it's a memory leak, because when leaving the room, memory drops back to before entering the room.
It's a pity you don't sell more of this package. I don't think most GameMaker users know how dangerous the ds_* can be, even when you just do a genuine mistake.
Thanks again for everything, especially GMLive and GMEdit which is my daily driver IDE.
