No, I have not made any changes to the css.

Same problem.

I even removed the external style sheets that I was loading and that just caused the containing div to go fullscreen with no horizontal scoll bar, in other words, the grid went off the screen to the right.

The data rows are the expected size, but everything else is the same width as if all of of the columns were showing.

Thanks

Yeah, sorry.
