Stability and compatability issues on windows xp

Hi all,

I've recently upgraded from postgresql 9.0 (with pgadmin 1.12 of that
time) to most current 9.4.4-3 binary windows release from enterprisedb.
And surprisingly, I'm now fighting hard with the new pgadmin.
I'm on windows xp sp3 (32-bit).

The issues are:

- pgadmin from enterprisedb's binary installer (1.20.0) starts
correctly, but some few trivial clicks through tabs and buttons cause it
to eat up 100% CPU and become unresponsive to the point where the only
choice is to kill it (in under 1 minute). Looks like maybe a wxwindows
problem.

- pgadmin 1.20.0 from the standalone installer
(https://ftp.postgresql.org/pub/pgadmin3/release/v1.20.0/win32/pgadmin3-1.20.0.zip)
refuses to start, because the executable binary header indicates a
requirement for windows vista or above. Not sure if the requirement is
real, but windows xp wouldn't start it anyway.

- pgadmin 1.18.1 from the standalone installer
(https://ftp.postgresql.org/pub/pgadmin3/release/v1.20.0/win32/pgadmin3-1.18.1.zip)
starts, but exhibits the same problem with 100% CPU load and
unresponsiveness, and also complains about unsupported postgresql 9.4

- pgadmin 1.12.1 from enterprisedb's 9.0 binary windows installer still
works fine for me (except for very rare sporadic crashes) but it does
not support postgresql 9.4 features correctly.

So I'm wondering, is it supposed that windows xp has to be immediately
abandoned, or maybe nobody is much interested in testing/using on
windows platform altogether anymore so issues on windows just do not get
discovered?
Ok, still, maybe any ideas on how I could try to get at least some
reasonably new pgamdin version usable on windows xp (and not eating 100%
CPU fulltime)?

Any hints much appreciated,

Thank you,
Nikolai
