IGS Read bug in v6.9

Hi, Is there anyone reply here!

I am trying to open an igs file in mfc imporeexport sample project, which was fine with occ 6.1, (the file contain a simple surface generated from a few points), but in the new version (occ6.9 & VC10sp1 64bit) sometimes it works! but after clicking on dynamic button and rotate it the following error occures:

Unhandled exception at 0x000007fefdb4aa7d in ImportExport.exe: Microsoft C++ exception: Standard_NumericError at memory location 0x001cd748..

could you please help me what the error is related to?

Best regards,

opened the IGES file in MFC samples Import/export. Its opening and dynamic rotation also produced no exception:)

So, is there something wrong with my installation or hardware?
