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 
Windows then? 
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.
