I'm using RubyMine 4.5.4 trial on Windows 7 Enterprise Edition 64bit.
Right after I open a single quote after typing require_relative the autocomplete kicks in and hangs RubyMine completely.
The only thing which is left for me to do is launch task manager and end process.
I tried to reinstall and it didn't help.
My laptop specs are core i7 based processor and 8GB RAM.
*It seems that older version of RubyMine 3.x works perfectly fine in this scenario.
*I just checked RubyMine 5 beta and it hangs in this scenario but after few seconds it comes back so no need for killing the process.
