A user running my software on 2 separate computers for several months has reported that an access violation has suddenly started occurring on both computers when simply minimizing the application.
I gave him a build with MadExcept compiled in, and he sent this crash report. exception message : Access violation at address 004BBE48 in module 'MyProgram.exe'. Read of address 3D579DE8.
