I bought a Logitech wireless keyboard and a trackball and ran their
Unifying program to make the keyboard run in parallel on the
trackball's USB transceiver. That works fine, but now the keyboard
won't talk to the dongle it came with.

The keyboard and trackball remained 'Unified' when moved to a
different Win7 computer. I suspect the program copied the trackball
dongle's recognition code to the keyboard.

Since I don't need/want-to use a different keyboard, as long as
the trackball doesn't get confused with another in the same room (my
wife's potential one) it will be fine.

I just operated the cursor simultaneously with the trackball, the
touchpad on the wireless keyboard, and another wireless mouse. The
only wireless interference I've seen was from an aftermarket laptop
power supply that also jams the converter box for my old TV and shows
a wild party of spurious radiation on the spectrum analyzer.

I don't own anything Mac or *nix to try it on. At Mitre I had a
Windows PC, a Mac, a Sun and a Novell network in my lab, set up for
different CAD tools. Windows was by far the most versatile if not the
absolute best for every task. The Mac was particularly difficult to
add custom circuit boards to, not for the NuBus which is easy but for
the complex driver requirements. Windows doesn't like the user
executing low-level I/O instructions either but it allows anything in
DOS, which is still in there. I don't type fast or well enough to be
comfortable with Unix.

Well ... I started with all-text OS's, and unix (at that time)
required less typing (e.g. "mv" instead of "MOVE" or "RENAME"), but
today there are excellent GUIs on pretty much any unix flavor. I still
like to use older programs which do want to be typed to, but my typing
speed is fairly reasonable since I was actually using typewriters at
home as a teen long before computers at home were an option. :-)

In fact the DOS underlying Windows 7 is rather nice, and almost fully
compatible with long NTFS file names etc. I've been using DOS batch
files instead of NTFS scripts to automate my backup process.

Any problems with files with embedded spaces? I understand that
is a problem even in Windows with scripts. And is certainly a pain with
unix. (Though there are work-arounds. :-)

And there are now some pretty nice CAD and schematic capture
programs on linux -- more than on Sun's Solaris -- unless you are
willing to spend more than a car used to cost for a single seat license. :-)

Enjoy,
DoN.
