Hi , I want to show a message when the user clicks on a website wich is coded with a html file
Html file
	
	
	
	
	
	
	
		
			
			
			
			
			
		
	
	
	
		
	
	
		
	
B4a Code
	
	
	
	
	
	
	
		
			
			
			
			
			
		
	
	
	
		
	
	
		
	
The sub grabs the link and looks for jpg and mp3 this works fine
When the flickr link is pressed , the Msgbox = shown but it's
shown twice , also when the user clicks a link on the flickr site
the Msgbox is shown.
Is it possible to show the Msgbox once ,and only when you leave
the app .
