Starting Klayout and open a GDS file works fine.
However after closing the file and then open another GDS file, the layout window is never opened for the new file.
If there is a method to show the second layout, I have not yet found it.
My only solution is now to terminate Klayout and start it again, to open the next GDS design.
Is this a known behaviour?
