Firefox not generating filtering list

Suite and Optimus Suite 5

When using firefox the combo box doesn’t generate the suggestion list when typing into the box. I can force the suggestions to appear by typing then clicking into the box when the list then appears. It works fine on IE but doesn’t seem to work on firefox.

I’m using DHTMLX2.6 and firefox 3.6

Is the problem reproduced in the standard sample ? For example:

dhtmlxCombo/samples/04_filtering/02_combo_filter.html
