Given the absence of virtual memory and the generous 640K limit, I don't > think each cell is a window. Actually, it's even worse than that. When a window is created, a data structure of non-trivial size (I don't know exactly how large) is allocated from a single 64K segment, which is also used to allocate class structures from. (HINT: This is why you shouldn't register window classes with large cbClsExtra or cbWndExtra values) --Bill Turner (bturner@hp-pcd.hp.com) HP Corvallis Information Systems
