update. I think win2003 is good afterall. seems like the problem was that the prosess is not runned when restarting os. so I shceduled task to run up the dispacher on boot, on logon, and every 5min. seems to work ok. if dispatcher allready runs it just exits so no worrys about multiple dispatchers appearing.
however win7,win2008, win2008 with compabilitysettings is still no good. Please update software to be stable under newer windows os'es....
