Following on from my original posting relating to scrolling issues
I have now tripped over another scenario whereby the frozen column scrolls independently of the other rows.
To illustrate the problem I have created the following
If you run this dojo and select the first checkbox then using the keyboard tab through the other checkboxes.
As you traverse down the checkboxes the rows in the frozen column will start to scroll but the other rows remain static causing major synchronization issues between the two tables.
