I have a superbitmap window. An assembly lang. routine is operating
directly on the bits of the bitmap. Now and then I copy
the bitmap into the window with CopySBitMap ( I'm not sure about the
routine name but its the one that updates the layer to match the bitmap)
I discovered that it is necessary to LockLayer(mywindowslayer)
and then catch MENUVERIFY|SIZEVERIFY. 
Heren lies the problem: How do I know when the MenuEvent is
done and I can LockLayer safely?(ie. without deadlocking Intuition)
problem two: I want the window dragable, how do I DRAGVERIFY?

anyhelp would be apppreciated.

Is it necessary to surround the assemblylang routine with
LockLayer/UnlockLayer?
