Editors freeze when opening new view with Ctrl+2

Hi,

Past days it happened several times to me. Opening a new view for my RPGLE
source (in iProject) results in a frozen editor.
When this happens I can not use any of the other views on the screen, they
are also frozen.
The menu's in the top of the application do work, so I can quit the
application in a normal way and restart it. But is annoying.
I'm on 9.6.0.1.

Anyone seen a similar behavior?

Regards,
Arco Simonse
