Yup, we got a bug then, and I know it sucks to throw all that work away, I think someone mentioned a patch, maybe that would do it, by the way I tried it, it does crash as you said. Found a cheesy fix though, in the interactivechange method:

if this.listIndex= 1789
	this.listIndex= 1790
endif

Of course you'd have to fill item 1789 with something you don't want selected such as "-------", or whatever, maybe just leave it blank, worked here, HTH.

We can type a policy number and the combobox changes so that the policy is the first column and if the user types a letter, the name becomes the first column. As the user types as fast or slow as they want, we autofill(search) for them. It is really fast and works very slick.
