disabling sort feature, yet it still runs a sort process

Hi,

Using grid v1 here, and I have this in my code...
obj.sort = function (index, direction) { return "disabled"; };

to disable sorting. However, when I click a header, a process is still run,which takes about 15 seconds or so on the large data set I'm presenting, and the window status switches to "Sorting..." during that process. This is annoying because it basically freezes my page for 15 seconds while it completes a process that does nothing, since sorting is disabled. Anyone have a remedy for this?

Thanks

Meant to post this is v1.0 forum, sorry, I'll repost it there.
