Any application that relies solely upon WNE for event handling will indeed
have limitations, and not just related to composited windows. However, I'm
not aware of any reason a WNE framework would be incompatible with
composited windows as long as the standard handler is installed on those
windows. I don't use a commercial framework, but my application still uses
WNE and most of my windows are composited. Off the top of my head I can't
think of anything super special I'm doing to get composited windows to work
with WNE. Would you care to describe specific incompatibilities, i.e.,
exactly what you think won't work in a WNE framework?
