Thank you, man.

Sure, I'll do in deep tests to see what/why/how.

Can somebody, please, reproduce this and give it a bug number?

[quote="Peke"]Have you tried to unregister Timer?[/quote]
Yeah, I used [b][i]Script.UnRegisterAllEvents[/i][/b], but it didn't work.

From what I see Timer/event is triggered even Script is terminated.

Have you tried to unregister Timer?

Error executing script event
Invalid pointer operation

Dim bHalt
bHalt = False

Sub StartSearch(oPanel, sSearchTerm, sSearchArtist, sSearchAlbum)
 	Script.RegisterEvent SDB.CreateTimer(0), "OnTimer", "Timeout"
End Sub

Sub FinishSearch(oPanel)
	bHalt = True
	Script.UnRegisterAllEvents
End Sub

Sub Timeout(tTimer)

	tTimer.Enabled = False
	
	SDB.Tools.Sleep(1000)
	
	SDB.ProcessMessages
	
	If bHalt Then
		msgbox("Halted! but will throw an error!")
	Else
		tTimer.Enabled = True
	End If
	
End Sub

When a Search Script calls [b][i]SDB.ProcessMessages[/i][/b] from a timer and the Auto-tag window is closed MM throws an error:
[code]Error executing script event
Invalid pointer operation[/code]

This is a sample script:

[code]Dim bHalt
bHalt = False

Sub StartSearch(oPanel, sSearchTerm, sSearchArtist, sSearchAlbum)
Script.RegisterEvent SDB.CreateTimer(0), "OnTimer", "Timeout"
End Sub

Sub FinishSearch(oPanel)
bHalt = True
Script.UnRegisterAllEvents
End Sub

Sub Timeout(tTimer)

tTimer.Enabled = False

SDB.Tools.Sleep(1000)

SDB.ProcessMessages

If bHalt Then
msgbox("Halted! but will throw an error!")
Else
tTimer.Enabled = True
End If

End Sub[/code]
