Hello,
thank you very much for your reply.
I followed your suggestion and I tested again my debug program
attached in my previous message.
Yes, I confirm that it takes long time for opening the file dialog.
It's something between 30 and 40 seconds and this time repeats more or
less when I press some control or I select some items.

Sincerely,

Carlo Bramini.
