As you wrote - the debug-exe works, that release-exe crashs
Trying to compile this, i get a:
Fehler XS1703 Multiple assemblies with equivalent identity have been imported: 'C:\Windows\Microsoft.NET\Framework64\v4.0.30319\mscorlib.dll' and 'C:\Windows\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll'. Remove one of the duplicate references. ZedGraphVS XSC 1
No idea, where to look for this...
BTW, are the references to VN needed?
