Hi, thank you for your reply.
I have not yet had time to try your suggestions
but I have another peculiarity to report:
I have created fences and set the transparency
to zero but in spite of this when I click an icon
in the fence I most of the time activate the
icon that is behind on the desktop. Annoying….
This is an upgrade from a previous version
(4.21 I think) which had none of these problems.
Best rgds
Stefan
