[Remind-Fans] A problem under XFCE desktop manager

[Paul Smith]

Dear All

I have successfully used remind for a long time together with KDE, but
now that I am migrating from KDE to XFCE, I am experiencing a problem:
the window of the reminder

REM Friday AT 22:10 RUN xmessage -center "I am trying this"
REM Friday AT 22:10 RUN beep

does not pop up.

I have issued the command

xmessage -center "I am trying this"

in the console and the window pops up correctly.

Any ideas?

Thanks in advance,

Paul
