Re: can't use windows with GoBack?

[Lester Ingber <ingber at ingber dot com>]

Harold:

Until this GoBack problem occurred, I was using
XWin -unixkill -emulate3buttons -clipboard -rootless &
wmaker &

I also used a few xterm commands, with very good performance:
xterm -sb -bg white -fg darkblue -cr red -ms red -bd red -geometry 80x84+91+0 -name left &
xterm -sb -bg white -fg darkblue -cr red -ms red -bd red -geometry 80x84+592+0 -name center &
xterm -sb -bg white -fg darkblue -cr red -ms red -bd red -geometry 80x84-0+0 -name right &
xterm -sb -bg white -fg darkblue -cr red -ms red -bd red -geometry 250x84-0+0 -name large &

After I installed GoBack, I hit the terrible/impossible performance.
I found that
XWin -unixkill -emulate3buttons -clipboard -multiwindow &
and with even 1 or 2 xterm windows was just a bit better, but still miserable.

I tried your suggestions:
XWin -engine 1 -unixkill -emulate3buttons -clipboard -multiwindow &
XWin -fullscreen -emulate3buttons -clipboard &
with just one xterm window, but these seem just as slow.  (The fullscreen
would not be so good for me as I often need multiple windows.)

I disabled GoBack, rebooted as required, and I'm now running
XWin -unixkill -emulate3buttons -clipboard -multiwindow &
just fine.

I noted that with or without GoBack my browsers and other PC applications
seemed to work fine.  Of course, when I brought up any XWin tool, all
performance was degraded due to the load on the System.

I appreciate your trying to help.
Thanks.

Lester
