I'm using jqGrid 4.4.4 with jQueryUI 1.10.0 and jQuery 1.9.0.

I have a grid with tree columns and the third one has fixed width. In some cases I empty the grid and I load new rows and all works well.

Now, if I sort rows with drag&drop and then I empty grid loading new values, I get all columns with the same width (but the column headers width is still correct).

With jqGrid 4.4.1, jQueryUI 1.8.16 and jQuery 1.7.2 it works perfectly.
