When switching from program X (for example Outlook) back to Diamonds, Diamonds seems to block. He’s stuck.
Eventhough it was working fine 5min before.
This issue particulary occurs on Windows 11.
Solution
When you select Diamonds again, it will ask Windows for the print properties… But Windows 11 determines the preferred printer automatically. And when that automatic process takes too long, Diamonds will refuse to work.
The solution is to change the default printer to a local printer.
