First of all, thanks for editing and developping a such masterpiece which is Sublime Text 2.
Secondly, i already got this issue on version 2139 so i gave a try to the dev version (2143) but the crash is still here.
Sublime text 2 crashed (on windows) when the user try to write while Sublime text2 prompts a list of terms.
My configuration : Windows 7 x64 SP1.
ps: sorry for my poor english.
