I had the bright idea of compiling the source myself, using SAS/C on OS3.9, and not link the original lib, from Stephan Rupprecht's source above. The window opens, gadgets laid out, won't respond to any input.
From what I can tell this call
Code:
GetAttrs(Objects[OID_WINDOW],
WINDOW_SigMask, &SignalsMask,
TAG_DONE);
isn't been handled correctly??? The next call, Wait(), doesn't get any signals.
