That dialog should require > pressing a button to dismiss it. I think if the process dies or exits, the dialog is closed. So, since you seem to be able to reproduce this with a simpler setup, please try these: . repeat the experiment using 'SIGINT and 'SIGBREAK instead of 'SIGHUP . repeat the experiment with w32-start-process-share-console set to a non-nil value (both with SIGHUP and the other 2 SIG* signals) I'd be interested to know whether the results are different. (If you have no time for these experiments, just leave this until I get to testing the branch. TIA.)
