jQuery Grid Plugin - jqGrid

Worked all night on this one, but giving up and need help.

If you go to any of the jqGrid demos in IE 7 or 8 and start clicking on reload icon, you will see memory in task manager for IE will start creeping up.

I looked in sIEve explorer and it looks like jqGrid is leaving orphan <tr> objects in IE. This is only an IE thing.

I tried modifying ReloadGrid function by emptying inner and outer HTML on all rows but it helped very little if even.

My application refreshes the grid every 15 seconds and after running it for 2 hours the memory usage increase is considerable so i need a solution.

Did anyone else experienced this fluke? How to approach it?

BTW: i am using deepempty option, it does not help unfortunately.
