"An outgoing call could not be made since the application is dispatching an input-synchronous call."
Has anyone else seen this? The script works with SilkTest 5.5 and even 6.0beta, but not 6.0. I've talked to Segue support and they've been unable to provide a workaround or even been able to reproduce this same error.
Thanks for your reply! Unfortunately, that didn't work because using typekeys as you have was always just selecting the first item of the drop-down menu that started with that letter.
Segue support did (finally) provide a workaround that works! The window identifier recorder picks up the control as CustomWin("[ComboLBox]#1"). So instead of Window.SomeHtmlPopupList.Select("Item") you could do Window.CustomWin("[ComboLBox]#1").TypeKeys("<Down n>"), where n is however many times you have to push down to get to the item you want to select.
