I have a problem with my debugger. (or more likely a setting) When I attempt to debug my code, all my breakpoints claim to be invalid (when I know they aren''t) I also get a popup with half a message on it ! The text I can read is, \..path info\OpenGL Template\WinRel\MfcOGL.exe does not contain" Damn, thats frustrating. Any ideas. ? I would look on Technet, but as I have no error code, all the guesses I have used for search strings have failed. TIA, Bp.
