It's not freed immediately on exit from the routine; it's more left unused and unreferenced by the side of the road and eventually the garbage collecter frees it for you, either when things are quiet or when memory supply runs low.

Click to expand... Lol I did wonder if maybe it was a global even though your mention of Dimming it in a Sub made it sound like a local variable. If it is a global, then initializing it after you've finished using it should cause it to lose hold of any memory that it previously had allocated to it, and that now-unreferenced memory will eventually be gathered up by the garbage collector for reuse. (Re-)initializing a Bitmap Creator object will probably also cause it to allocate some new memory, but I would except that to be fairly small if you stipulated new dimensions of eg 1 x 1.
