Hello!

I've found a problem using grids with “true scrolling” (scroll:1)

… in some situations some rows (full pages) get displayed twice. This happens when using a small page size (rowNum:10) with a big dataset on the server (200 rows) and scrolling a lot in both directions – especially when dragging the scrollbar so that pages are skipped or directly loaded.

[Maybe you could also try to change your “true scrolling” online demo sample or provide another one with a smaller page size (rowNum) than the displayed rows – e.g.: rowNum:10 and make the grid bigger to display about 25 rows]

The resulting rownumbers of such a problematic situation are: …, 18,19,20,21,22,23,24,25,26,27,28,29,30,21,22,23,…
When looking into the DOM tree the rows are really duplicate there … 1-30,21-40,31-40
… so there are full pages twice in the DOM and also visible in the tree.

I'm working with the latest release 3.6.4 of jqgrid and jquery 1.4.2.

After browsing the forum I've read about updates at github with scrolling and also have tried the latest trunk version from there.
Also with this source version I can reproduce the problem, but detected other problems with this devel-code:

• on initial load of a table with true-scrolling I sometimes get negative row numbers for the first page: -9…0,11-20…
• the grid resizing now works in another way incorrect: previously the last column got shrunk in width –> NOW: the first columns are getting smaller and smaller with every resize until they are min sized to a few pixels. The space is taken from the next fix-sized column

Kind regards,
Klaus.
