I recently created a dashboard and pasted several tables as linked pictures (column and row width just were not allowing me to get where I wanted). It looks great but scrolling is just about terrible sometimes. Usually if i scroll down with the mouse it refreshes every second for a few seconds. Its quite annoying and looking at excel.exe's resources, its hardly anything. However, sometimes the dashboard scrolls very well just as a regular spreadsheet. What is causing this irritating choppy lag while scrolling?
