Hi Friedrich,

what are the correct Parameter Types for the Windows function
CreateMutex (
http://msdn.microsoft.com/en-us/libr...11(VS.85).aspx )?

I tried *LONG,INT,*STRING (and a few other combinations) with the
Function Parameters 0,0,%MUTEX_NAME%, but I get WinLastError 87 (
http://msdn.microsoft.com/en-us/libr...(v=vs.85).aspx
) very often (but not every time) on WinXP x86 SP2.

Thanks for your help.

Markus
