I sometimes have four instances of pmail running parallel.
Since today, in one of the instances, I have a problem with opening emails. The other instances work correctly.
When I click on a mail to open it, it seems something is happening by the turning time-clock / mouse pointer being busy. Because of that I think the email opens, but I cannot see it. Or opening the mail does not succeed and there is no error message.
Restarting does not work, checking for messages outside the pmail frame also not, making it extended monitors also not.
However, when I start a new message either through the menu or through ctr-n, it works without problem.
Running 4.8 with IERenderer 18.104.22.168 enabled. Disabling it does not help either.
