DropdownListBox selection problem

Hi together,

we are running several bsp applications with of course htmlb:dropdownListBoxs.

A short time ago we update our systems from CRM 4.0 to CRM 5.0 with WAS 700 SP8.

Now we have problems with our htmlb:dropdownListBoxs. If the user selects a DDL and type e.g. a 'E' it should select the first entry starting with a 'E' in the DDL value list. In 4.0 it works well, but now in 5.0 it dose'nt work anymore.

It concerns all bsp applications including our PC UI apps.

Any ideas?

Thanks in advance, Stephan
