Scrolling in different tabs

There's this really annoying thing in Opencart Manager, that prevents you from scrolling in different windows just by hovering over them. This mechanism is normal all across MS Windows, but in OM you have to actually click somewhere in the window to activate it. When you enter hundreds of data every day, than this is like the most frustrating and counterproductive thing ever.

Also, when you edit description of product in one window and scroll, previously active window (like products list) also scrolls. Sometimes it's sooo frustrating.

This would be much appreciated if you guys could manage to update the scrolling mechanism in Opencart Manager.

Thanks,
Piotr
