And once you are running Windows, you can run XTree Gold either full-screen or in a window. First of all install XTree: in the Program Manager click on a group, such as Main, where you want to install XTree. Select File, New, fill in a suitable program description to appear beneath the icon, and for the command line enter "C:\XTGOLD\XTGOLD.COM /XM", then change the icon to C:\XTGOLD\XTGOLD.ICO. XTree can now be started in any of the normal Windows ways. It will normally come up as a full screen.
To change XTree to run in a window, key Alt-Rtn. This is a toggle, so a further Alt-Rtn will revert to full-screen mode. Incidentally, the books say you should use Alt-Enter; this doesn't work on my machine.
You can cycle through all the open programs with Alt-Tab: keep one finger on the Alt key, hit Tab repeatedly, and release Alt when the screen tells you that you have arrived at the desired program.
