Warning when scrolling ListGrid

[Sytematic]

Hello,

I am using (SC_SNAPSHOT-2011-03-13/PowerEdition Deployment 2011-03-13), with Mozilla Firefox 3.6.15.

When I scroll my listgrid I get the following warning all the time. My application seems to just work with the warning, but I wonder where this comes from.

I was unable to isolate exactly what piece of code caused it, so I wonder if someone could give a hint according to the warning message below?

This warning is spurious, and has now been removed. Thanks for the report.
