Welcome screen appears over and over again

[uwemock]

Some time ago, XNote started to show the welcome screen over and over again, almost each time I open Thunderbird. Meanwhile, I found out that this seems to happen when I have opened Thunderbird from another machine. I.e. I open Thunderbird on client A, welcome screen appears, I close it. When I re-open Thunderbird on the same machine, the welcome screen does not appear again. When I now open Thunderbird on client B, the welcome screen appears. The welcome screen will thenn reappear when I'm back on client A.

Could you please resolve this?

My XNote version is 3.2.10.
