The not-so-good precursor: On that said day, my trial version of goScreen (or rather, a very central part of it, the desktop maps) stopped working without prior warning (very unusual for shareware) – unfortunately in a very bad moment for me! There was no way to make it temporarily work again (e.g. by prolonging the trial period), so I had to wait for my license to arrive to continue using goScreen. The good outcome: Andrei was very understanding, responsive and co-operative and sent me my key within exceptionally short time. That saved my day and work, Andrei! Thanks again!
