So, it's really a result of the rapid change of Linux apps, this synching
problem between libraries and apps?

My problem is that new apps won't run on old distro's... you have explained
that's because the new apps have new demands. Right?

Oh, so they have to mess with the source code and re-compile things to meet
older library supplies.

Alright. I get the overall impression of a wild, crazy, tazmanian devil ball
of whirling software shooting across space. The change is rapid and
unpredictable and it's amazing what the distros do to produce
working "snapshots" of this mayhem every now and then.
What is the reason for the seeming stability (i.e. backwards support) of
I have read recently (can't find link) about how hard Microsoft has to work to
keep backwards compat going. Apparently they even hardcoded special cases
into their kernel to run games like Sim City (or The Sims, I forget). So the
answer to my question could be exactly this: Microsoft has made it a mission
to keep compatibility, but Linux being mostly unpaid and chaotic has no such
Still, seen from the pov of Windows, is it unnatural to want to move to newer
version of software you need and use but *not* want to have to face an entire
O/S upgrade (with hellish complexity) every time? It seems like a real
problem, a catch-22. I know it causes me stress and I'm a 100% Linux user. I
had another friend who tried Ubuntu for a while but got so irritated that she
could not go to new versions (of FF and Thunderbird) that she gave up.
Thx for the info.
