All of this should be acheivable, but since I don't know what isl you are using, I can't tell you what in the isl is causing these settings. There are any number of roles that could be causing the grid to HotTrack. What I would do is open up the isl in AppStylist and go to the grid tab. Mouse over a grid row and look at the list of roles that come up in the tooltip. Examine each role listed and see which one has settings applied to it. Specifically, check for the HotTracking state on the tabs at the bottom. 

Thanks for that.

Switching off the style library does indeed stop hot tracking. I was using just one of the example templates styles which seems to bring on hot tracking and I couldn't work out how to stop it in the the App Style.

I also wanted the row selection to switch off i.e, just for a selected cell to be highlighted. I did this by editing the style library so that selected row appearance was the same as normal, unseleced row appearance which I think was a bit of a hack.

In fact, what I want is something that selects like Excel, so that I can work at cell level. No hot tracking of rows or cells and when a cell is clicked only that cell is highlighed and not its entire row.

 Thanks.
