I'm working on a medium-sized Windows application (~20,000 lines) using
SDK 2.1, and I'm running into a bizarre problem.  I have a dialog module
for opening a file; it works fine for opening an application's main data
file.  However, when I call it from another dialog box procedure (to open
an auxiliary file), it appears OK, and I can select a file no problem,
but it won't go away.  When the file dialog procedure processes the OK or
Cancel message, it never returns from the EndDialog() call!  More exactly,
it destroys the file dialog box from the screen, but immediately creates
another file dialog, and then another, until finally I get a stack overflow. 
Ctrl-Alt-Del is  the only way out --- and yet the file dialog box works fine
for the other, my main File Open call.

I've been spending hours on this, and endless reading of docs -- what could
I be doing wrong?  I'm quite sure I'm allowed to have a modal dialog box
call another modal dialog box --- that's the way Printer Setup works, too!
Where can I look?

I can send a code segment to anyone who's willing to look at it...
