	Help!
	I'm trying to use layers with an Intuition window.  What I wanty
	to do is create my own 1024 x 1024 bitmap, and scroll it around
	inside an Intuition window.  I have succeded in scrolling the window,
	but whenever I size the window and move (drag) it, portions of my
	bitmap gat blanked out!  Heres what I'm doing:

	* InitBitMap()
	* Create 1024 x 1024 bitmap w/calls to AllocRaster
	* Assign BitMap to NewWindow structure
	* Call OpenWindow(NewWindow)
	* Obtain a pointer to Layer from Window->RPort->Layer
	* Obtain a point to a Layer_Info from Layer->LayerInfo

	Using proportional gadgets I've created to scroll the layer works
	great.  I just make calls like:
		ScrollLayer(LayerInfo, Layer, deltaX, deltaY)
	(can't remember order of args just now...)

	That all works fine, but when I size and drag the window, portions
	of my bitmap get cleared to (I think) the background pen color!

		Thanks in advance,

		Steve Sanderson
