VS 2010 C++ DrawText function ignores font selected for HDC.

This is a problem I have beating my head against for 6 months. I'm hoping that someone else has encountered this issue and found either a solution or a workaround.

I am using VS 2010 C++ Express to develop W32 apps on a PC running 64-bit Win 7 Home edition. A chronic problem I encounter w/ all such apps is that the release *.exe will INTERMITTENTLY substitute the system font in lieu of the specified font when rendering text using the DrawText function.

The problem never occurs while running the app under Debug in the IDE. The problem manifests only with the release *.exe running in the following environments:

Occasionally running from VS 2010 IDE
More frequently running from a directory on same PC hosting VS 2010.
Still more frequently on another PC running
64-bit Win 7 Professional Edition.
or 32-bit Win 7 Home Edition
or XP w/ SP3
or Win NT

The problem ONLY occurs in a Dialog callback that uses TextOut() to write to its own window. All fonts are created using CreateFontIndirect() referencing a LOGFONT structure.

There appears to be no pattern to occurrences. The problem will manifest only for some (but not all) uses of DrawText () in a single call to the callback.

Sometimes the problem will manifest in the 2nd or 3rd call to the callback. At other times, the problem will not occur until the callback has been called 20 or more times. A single occurrence may manifest on one call to callback followed by multiple callback calls w/o any occurrences. I.e., the issues does not appear to be related to a memory leakage, stack overflow or inadequate heap space.

Solutions I have tried.
(1) Font created one time as a global variable by main WinProc.
vs. Font created one time as a static variable by main WinProc (and passed to callback)
vs. Font created one time as a static variable in callback under WM_INITDIALOG.
vs. Font created/destroyed as a static variable in callback on each all call to callback.
vs. Font created/destroyed as a non-static variable in callback before and following each reference to DrawText (). This config seems to work best.

(2) Tried all combinations of large and small values for stack size and heap size under Linker -> System. Minimum values for each seem to work best.

Can anyone help?
