Scala SBT Shell clear button is deactivated


after updating to the newest version I cannot clear the sbt shell anymore, as the bin-button has been disabled:

The Event Log does not show any warnings nor errors. Did anybody else experienced this behavior?


Are there any plugins which might interfere with this functionality. I have installed the GREP-Console plugin.


Thanks in advance


I haven't seen or heard of this problem yet. Does it persist across project or IDE sessions?
