[4.0.2a] Grid scroll issue. Scroll bar not working in grouping grid
I am using Extjs 4.0.2a. I used grid grouping so scroll bar appears when it exceeds the height. After Click collapse button in the grouping grid until the scroll bar disappears from the screen. After 1 or 2 minutes click on the expand button. Now scroll bar appears but scroll bar is not working.
The scrolling system is changed in ExtJs 4.1. Probably you get a different behaviour if you upgrade to 4.1. There were a lot of bug with scrollers so they changed it by using native browser scrollers in 4.1
