Sorry to repost, but there were no responses to my first post and I am growing desparate.

See: http://www.codeguru.com/forum/showthread.php?t=474843

Visual Studio 2005 C++ (WinXPPro) works just fine with the single exception that I am unable to write to the Output window using TRACE macros, _RPT macros, or the Win API OutputDebugString(LPCTSTR ..).

Using the Win API function BOOL IsDebuggerPresent() indicates the a debugger is present when the compiler is run in the Debug mode, yet no debug information is sent to the output window, only the usual stuff that is sent in Release mode.

This problem occured suddenly about 2 weeks ago. I cannot associate it with anything else that I might have done.

Any thoughts or ideas greatly appreciated. (There is no 'desperate' icon or I would post it here!)
