Why Timer Stops For 1st Selected Item In Combo Box

Visual Basic Express Edition 2008 Problem. I have a Combo Box containing Country Names "New York" & "New Zealand", when "New York" is selected it shows the time and date of New York in label1 on the form and the time is updated every second by the timer, but when I make another selection by selecting New Zealand in the combox dropdown list then New York's time updation is stopped in label 1 and only New Zealand's time is updated in label 2. Why the timer control stops functioning for the first selection after we make a second selection in the combo box. I want that time for both label 1 country as well as label 2 country updates simultaneously on the form. My code is as follows:I have added 2 label controls and one combo box control on the form and following code.[code]Can any one advice me how all countries selected in the combo box one after other are dispplayed with updated time every second?
