Problem with sendFunction, doesnt work at second try

hi,

I've a problem with sendFunction,at this one when I use it repeatedly, doesnt work.. example:
the function is: send("!F") on Microsoft outlook, starts with:


WinActivate( "Inbox - Microsoft Outlook" ) ; Active Inbox - Microsoft Outlook
Sleep(1000)
Send("!F")
Sleep(1000)
....
...
etc...

and then, when the first step its done, i need to do it again, but, doesnt work


Thanks
