I've got an AutoCompleteExtender on one of my pages, it seems to be working fine aside from this strange behaviour:
Let's say I key in 2 characters, the suggestion list would display. When I press on backspace to delete those 2 characters, wait until the suggestion list to disappear, and re-enter those 2 characters, the suggestion list would no longer display (or sometimes would flicker for about a second after losing focus from the textbox) and I'll need to refresh the page just to get it working again.
However, if I do press backspace and delete those 2 characters but not let the suggestion list to disappear and re-enter new characters, it would continue displaying with correct suggestions. This behaviour seems to happen only in IE8, (although it works with IE8 using Compatibility View and Firefox)...
My code is almost the same as the sample on this site except for the animations, and the service looks up in a database table.
