Well... It shouldn't... The only way to make the scrollable area larger is by 
using theCanvas.configure(scrollregion=(x1, y1, x2, y2)); adding items into the 
canvas should have no effect at all on it...

Can you please post some (simple) code that shows this behaviour? Without a 
clear idea about what you're doing, it will be quite difficult to help you...
