Onhotkey event doing funny things

[Kevin Huber]

Hi
I have written the following code using the Onhotkey event:

ConnectEvent Application, "OnHotkey", "Onhotkey"
Function Onhotkey(hotkeyId, isBeforeAction, defaultActionAborted)
       If hotkeyId = HKNextLine And not isBeforeAction Then
sleep 500
ExecuteHotkey(hkStatusLine)
End If
       OnHotkey = false
End Function

However, if I replace the hotkeyID in the If statement by HKTitleApp,
then it works fine.
Why does the OnHotkey event seem to work for some hotkeys and not for others?
