Hi ,
It happens in both 4.5.1 and 4.6 preview for me regardless of project. It seems reproducible 100% of time. However, I will add that it’s not always instant. Sometimes lock-up occurs a few seconds after you open and click inside console window. (After doing this try clicking some where else in editor like class search text box). This is similar to behavior that MC Stryker describes in his question I linked above. He tries to select some text then goes to perform some other task (automation in his case but it doesn’t seem to matter for me) and then it locks up.
