#233 Lookup reaction problem and missing letters

[Lukas Voves]

I found a bug when you want to write text into lookup. If you focus on field with lookup and text cursor is not yet blinking and you start writing quickly, you write only the first letter and then some of the others get lost. After a while you can write with no missing letters. But it is very confusing and I didn't find any reason why is it loosing letters. It should be because of loading values from lookup.
