Intellij + Scala; it is with great regret...

Sadly, despite my expressed hopes, in appears the state of Intellij IDEA with Scala is not improving but worsening. This is sad. Each time you start up IDEA you still get a lovely internal error and exception stack trace. But worse, ever since the 8890 EAP build, the application hangs with any reasonably sized Scala project. This is even more sad. A colleague has confirmed this on his Mac, however, we are unable to revert to a usable version since you cannot download older EAP releases.

The suspected trend toward becoming more unusable for Intellij IDEA and Scala is regrettably confirmed. I wish it were not so ):

The Windows Vista upgrade to XP effect perhaps?
