    Description

      Sometimes, after using the function hint dropdown box whilst coding, the application crashes. This usually happens after the function hint closes and you click somewhere else in the code editor. This is not easy to reproduce, but happens about 1 time / hour on my machine. Below is the OSX crash report.
