# CotEditor crashes

In the case you are using ATOK, Shift-Return, which is one of the CotEditor's default key bindings, would conflict with ATOK's key binding and cause an application crash.
To solve this problem, you need to change the key binding of ATOK or CotEditor.
=> Key Bindings preferences
