Hi John,
Thanks for the reply. I created a minimal example (attached and
pasted). This example works fine in windows but doesn't show anything in
Linux. Also another thing I noticed in my original program is that when the
GUI is shown the list Controls in which I have added a lot of elements show
scroll bars also! But no elements are visible.
