Frozen column headers repeat in IE10

I have a grid with the first 3 column headers frozen. The grid is wide, so it has a horizontal scrollbar. I just noticed that in IE10, those frozen column headers are repeated in the non-frozen area, but the data is not, so the data does not match the column headers.

I just noticed that this particular code is using Pro version 2.6. I haven’t tried it yet in 3.5 (the latest I have).

Upgrading to ver 3.5 solves the issue.
