CodeCollab scrolling slow in all browsers except IE

We have files that are in the thousands of lines and opening them from an Inspection is very slow (we use Perforce if that makes a difference).  I can handle that, but scrolling is just as slow.  Click on the scroll arrow? Somewhere between 3 and 20 seconds before it scrolls, depending on the length of the file.  Click and hold?  Same thing, with those pauses in between each update.



Chrome (mac) is the worst; Chrome (win), Firefox (mac and win) are almost as bad.



IE (win) is good for scrolling.



Is there some setting I can use to make it faster?  Chrome mac is my browser of choice.
