Greetings, Werner & kl522

I think both suggestions are very appropriate, however

1- I don't know how to 'downgrade' something using Synaptic; and
2- I did not get a good feeling from browsing the LibreOffice site some time back
that there was any very well organized bug-repair activity there.

I recall Werner solved one lxmenu problem by downgrading, so that's surely
a possibility, but I'll need some tutoring.

Update: I just found 'Force Version' and am trying the 'stable' lxpanel offering.
Now, we'll have to wait for another upset to see how things progress.

Thanks, again.
