--- Comment #2 from François Gouget fgouget@codeweavers.com --- Note that the firewall alerts are very common but usually don't cause these user32:msg failures.
To take some recent examples: * 2023-04-01 w7u_2qxl-32 has the firewall dialog but not these failures https://testbot.winehq.org/JobDetails.pl?Key=131380&s101=1#k101
* 2023-04-01 w7pro64-64 has the firewall dialog and more and these failures https://testbot.winehq.org/JobDetails.pl?Key=131383&s101=1#k101
* 2023-03-31 w7u_de has only the firewall dialog and these failures https://testbot.winehq.org/JobDetails.pl?Key=131316&s102=1#k102
So the firewall and other dialogs appear to be red herrings.
Side note: you can find a bunch of runs with these failures there: https://testbot.winehq.org/FailureDetails.pl?Key=296
