The text in beanshell script check error dialogs should be selectable

When the Check script button is clicked in the beanshell script view, the text in the error dialog popup is not selectable, and hence cannot be copied.

Reported by Wil Koetsier (nikkimassa@gmail.com) :

I have a Beanshell that had an error: it wouldn't run. Luckily, there
is now a 'check script' function, which I really like (thanks!).
Picture 1 shows the message I got. Since I didn't spot the problem (if
you look closely, you will see that I am missing a ')' on the
highlighted line) and couldn't make sense of the error ('Encountered:
;') I wanted to google it. The problem here is that I am unable to
select the text from the dialog to copy it and paste in in Google.
