[MaxGUI] strange events...

Well, I want to know if anyone has my same result...
This is the 'standard' code that comes with the Bmax documentation relative to CreateListBox()

' createlistbox.bmx

Strict 

Local window:TGadget
Local listbox:TGadget

window=CreateWindow("My Window",30,20,200,200)

Const ETIP$="Greate for lovers of rain, mushy peas and stomping beats.~r~nNew line..."

listbox=CreateListBox(4,4,100,80,window)

AddGadgetItem listbox,"German"
AddGadgetItem listbox,"England",False,-1,ETIP
AddGadgetItem listbox,"French",False,-1,"tip - goes here","mystringobject"

SelectGadgetItem listbox,2

Print "SelectedGadgetItem()="+SelectedGadgetItem(listbox) '-1 means none selected

While WaitEvent()
	Print CurrentEvent.ToString()
	If EventSource()=listbox
		Print "SelectedGadgetItem()="+SelectedGadgetItem(listbox)
		If EventData()<>SelectedGadgetItem(listbox) Print "error with skidracer"
	EndIf
	Select EventID()
		Case EVENT_WINDOWCLOSE
			End
	End Select
Wend

Please run and tell me what events will be shown.
I receive

TimerTick: data=1, mods=0, x=0, y=0, extra=""
TimerTick: data=2, mods=0, x=0, y=0, extra=""
TimerTick: data=3, mods=0, x=0, y=0, extra=""
TimerTick: data=4, mods=0, x=0, y=0, extra=""

when I dont' move the mouse/click or anything else.
Why is there a Timer event in ListGadget? Or I mess up my source...
