combo widget

[Chris De Maeyer <chrisdm pandora be>]

Implemented a combo text widget with a rather large amount of strngs
inside (approx. 5000). Is it normal that it gets so slow, what
alternatively can cope with such amount of strings to select from?
Strings themselves are not too big (2 to 5 chars max). If possible post
example. 

Regards and thanks in advance for replies.
