I have the latest stable version of Webstorm on osx and since a couple of hours ago it became unusable. After only a couple of minutes of use, it completely freezes and the only solution is to force quit. CPU is at around 25% and memory under 1gb, so it doesn't seem to be a resource spike issue.
I've tried disabling all installed plugins and restarting my laptop, but the problem seems to persist.
Please let me know if you need me to provide some specific info for you to be able to troubleshoot this issue.
