Hello,

I do not know how to describe it or what it is related to.

When I start writing a code (such as a class name), it says "please wait" and then a list of possible classes is displayed.

Or, if I write a dot after the object name, the same is done, and then a list of related methods and fields is displayed.

Sometimes it happens that "please wait" is displayed for a few seconds and then it will throw an error.

*A java.lang.RuntimeException exception has occurred.*
*However, the system should continue working without further problems.*

Sometimes he does it only once, sometimes several times in a row.

Additionally, each error will add Saving snapshot,

 

which can not be canceled. (Only by closing the application)

This bug does not limit me, but it is quite annoying.

Please repair

Thank you
