I have a tabbed interface with Gridpanels on every tab. When I have multiple GridPanels using the same store, occasionally one of the Grid Panels will almost "lock up" and although the scrollbar will seem to move properly, the actual grid panel will not scroll down any further. This only happens sometimes, but it will only happen when there are two or more panels with the same store. It's rather confusing!
What do you suggest I do or try?
