Seesmic won't stop scrolling

When I click once on the scrollbar in a seesmic window, it won't stop scrolling. It trundles on for a few pages while a I click away on individual tweets until it stops. I have to use the little arrows at the top and bottom to go up one and down one tweet at a time but sometimes this will go into auto-pilot as well - arrghggh! This only happens in seesmic and happens nearly every time.
