Trouble with the xwin and ms remote desktop

[Matta, Sunil]

Jon: thanks for the response. And yes, Xwin definitely crashes.

On a desktop running Windows xp, started Xwin on a two monitor screen
with wmaker as the window manager.
Go home, connect to the desktop via a small laptop running xp as well.
I am connecting using xp's remote desktop facility : mstsc.exe.

Upon connection to the desktop screen, I see the xwin icon on the
taskbar, and then xserver immediately crashes.

Although, I just realized that the xwin root window is on screen 1,
which the laptop cant even see. Maybe that's why xwin crashes ???

I will try again after I move the xwin to screen 0 and let you know.


Also as a side, I have tried to use fvwm, but I don't see the usual
virtual desktops on the screen ???
Which is why I am using wmaker as the window manager.

Sunil
