The warnings show errors with respect to library calls. I have used it to trace what a programs does and what libraries it uses. If a call is made to a dependant library them Walker will show whether that call was valid or not. If there was a valid call then that DLL passes. Eroneous calls to DLL's may or may not show specific dependancies to the DLL in question BUT may show calls from other DLL's or EXE's which may be in error. In my particular case, the MFC42 dll in question was an NT specific version which caused BSOD exception errors in Win98SE. Replacing it with a Win98SE version fixed my problems. Your milage may vary. Good luck.

I backed mine up and put the smaller one in its place. Now warp13.exe works fine (at least after several tries of test cases that definitely did not work before). It remains to be seen if this smaller MFC42.dll causes other problems.
