>Here's a weird one. I have several edit boxes where this happens. I click in the box, press Ctrl-V to paste some text. The text appears in the box just fine. Then I leave the Edit box with the tab key or the mouse and the pasted text disappears. It doesn't happen when I enter the text with the keyboard or if there's already text in the field.

I've had some troubles like this. Are the Valid & Lostfocus firing, but text just isn't getting buffered? You can try This.value = This.value in the Lostfocus, see if that helps...
