This is a continuation of my last message.....

On further investigation, I was able to track down the reason for the 
strange colors, and even the solution.  It's interesting that this problem
appeared under Warp and not 2.11.  The reason for the error was that I
was following the procedures for modeless dialog boxes given in Petzold's
"OS/2 Presontation Manager Programming," and it appears that his 
suggestions are not sound.

The problem was that I was loading the dialog defined with the 
WINDOWTEMPLATE directive instead of a DLGTEMPLATE, and was using
WinDefWindowProc instead of WinDefDlgProc.  Apparently under 2.11
both methods give pale gray backgrounds to controls, whereas under Warp
the former gives a white background, and the latter a pale gray one.
Anyway, I appear to have solved my problem, but it bothers me that
Petzold gave some bad advice in his book.  

Hmmmm....

While I'm thinking about it, has anyone run across anything programming-wise
that worked under 2.1, but not under Warp?
