Yes, it is ok now.

It appears that on "Restart" Front Panel ends up in the +0 +0, upper left
corner of the screen. It starts ok, it is placed at the bottom center
part, but something relocates it in the last moment. I remember we had this
problem often introduced and then fixed again.

Now it seems that

"All (FrontPanel,CirculateHit) PlaceAgain" is causing the problem. That is,
it behaves differently that on fvwm3 1.0.4 and fvwm 2.6.9. It looks like
PlaceAgain is ignoring Style for panel:

PositionPlacement $[infostore.frontpanel.pos.placement]

... where infostore.frontpanel.pos.placement is "screen c 50-50w -0p ewmhiw=
a"
hardcoding this in styles instead of infostore variable doesn't change this=
.

A bit of more diagnostic:
If I execute PlaceAgain with FvwmCommand from terminal in this branch, Fron=
t
Panel (FvwmButtons) ends up on +0 +0. If I execute "Move screen c 50-50w -0=
p ewmhiwa"
it ends up where it needs to be.

Thanks, I will make it like that.

Now if I can only remember what I need to test, and what behaviour to expec=
t
from the FvwmPager. :-) I have set it up on two monitors now, and it looks
consistent on the both screens with and without "Monitor" setting. When
without "Monitor" setting, it shows both screens and it is horizontaly
wide. I have tried with DeskTopScale too, it is ok.
