Hmm thats to bad, i will try one of the workarounds, but as far as i know services are not supposed to create any windows anymore since vista. http://msdn.microsoft.com/en-us/library/windows/desktop/ms683502(v=vs.85).aspx "Important Services cannot directly interact with a user as of Windows Vista. Therefore, the techniques mentioned in the section titled Using an Interactive Service should not be used in new code." I wonder if the "Interactive Services Detection" kicks in on windows 7 if i run it as one of the workarounds. Gonna test now. Thanks for the answer, i will also add it to the wish list. I wonder if it might be included in the Enterprise Sync version? Or whatever that would be.
