column, grid, filter refreshing issues

Hello

I have a dhtmlXGridObject, with column sorting and headers, many of which contain #select_filters. I also enable enableLightMouseNavigation() and preventIECaching(true)

I have a javascript timer that uses ajax to refresh the grid once every 60 seconds.

Generally speaking it works as expected. I find two issues though that I have yet to figure out a resolution for.

Firstly, there are times when the mere act of rolling the mouse into the grid/rows area causes the entire grid to empty, forcing a full F5 browser refresh to repopulate it.
Secondly, oftentimes after a refresh, the #select_filter dropdowns are empty - not showing any of the values in the column to filter by. This too requires an F5 browser refresh to correct.

What might be causing these two issues?

Thanks!
Paul
