ctwm restart doesn't remember fullscreen state for all windowframes

[Van Ly <van.ly%SDF.ORG@localhost>]

Hello,

I use 5 workspaces in ctwm and of those 4 are fullscreen windowframes.

1 of 4 is an xterm in fullscreen.  When ctwm is restarted the fullscreen
state is preserved.

3 of 4 are emacs frames toggled fullscreen.  The fullscreen state is
lost on ctwm restart showing the desktop background at the bottom edge
about 50 pixels high.

Could I know where the likely root cause is and I will report feedback
to the right place for bug reporting?

Thank you.
