I frequently  use wireshark to analyze radius protocol on my work, and the
display filter is used frequently also.

In 1.2Pre1, the filter auto-hint feature is so interesting, I like it. But the
performance is trouble to me, because it's lag 2-3 second after type "radius.",
And more intolerable, if I type wrong expression, then want to correct it, I
type backspace, but when backspace to "radius.", it's lag 10+ second. 

for example, I want to put radius.User_Name but I type "radius.N" wrongly, so I
type backspace to delete "N", it's lag 10+.

I think it's should optimize the performance of auto-hint, especial when
backspace it.
