Well, they can use lots more memory. The code you posted doesn't handle
error conditions; is that what is going on? Two 160x140 8-bit windows chew
up lots of memory; wouldn't be surprising if you were out or nearly so.
If you don't have memory to create the offscreen windows, you'll have to
settle for not double-buffering or else you could refuse to run... but
that'd obviously be quite unfriendly.
