I created a table, where there are a couple of fixed columns, and the rest are scrolling. This is done using a wrapper div and setting position absolute and a negative left margin on the fixed columns.
It's part of a complex datatable so it's hard for me to recreate in jsfiddle, but here's a link: http://rateshopper.error404.ro/table.html
The problem is when you just play around with the scrolling and then move the cursor left. The fixed columns sometime just jump out of position. Unchecking and rechecking margin left in the inspector fixes it. I don't know why it happens.
Here's a video in Chrome: http://rateshopper.error404.ro/bug_chrome.mov
Any ideas or help would be greatly appreciated!
