Sorry, just realized that I didn't send this to the
list:
John,
I've been running the same examples in all of the
IDE's with the WX backend without any problems. I ran
them again when I saw this message. To the examples I
just add the two lines:
import matplotlib
matplotlib.use("WXAgg")
and all is well. Without these lines the graph
windows freeze (in WinXP).
However, after upgrading to version 0.5.4.2 there is a
new problem: after show() is run, the app quits and
the window disappears without any diagnostic output.
This happens with all of the examples that I've tried
so far. Before the upgrade they were working fine.
I haven't started debugging this yet. Any ideas?
System:
Win XP Pro, 1GB RAM, Pentium 4 2.6GHz
Python 2.3.3, GTK-Runtime-Environment-2.2.4-3,
pygtk-2.2.0-1.win32-py2.3
Regaards,
Barry Drake
