ScalaLab based on Scala 2.9RC3

Hi all,

I have a draft version of ScalaLab based on Scala 2.9 RC3
(http://code.google.com/p/scalalab/)

However, for some reason in ScalaLab console that operates the Scala
interpreter from Java, some Swing routines as
JOptionPane.showInputDialog stall the system,
while in ScalaCodeCells that is an interface written in Scala,
all operate well.

Can anyone understand the reason?

Cheers

Stergios
