Greetings,

I'm having a problem registering a window class inside a DLL...  It seems
to work for a "few" times (usually 3) but then it fails?

The RegisterClass call is inside the LibInit routine that gets called
at load time (as shown in Petzold ch. 18).  The return value of LibInit
is tied to the success of the RegisterClass.  If the RegisterClass fails,
LibInit returns 0 back to Windows at which time the spawn fails due
to "Not Enough Memory".  Numerous tests have confirmed that this is the
case, but I could be missing something.

Any ideas?

BTW, by symmetry, I would expect a LibUninit call also... does such a beast
exist?  Just Curious.

Thanks,
marco
