Trouble saving plots to file with 0.53.1

  Windows (NT4.0 and 2000)

    JDH,> * run this from the shell with

    JDH,> * see if the file testfig.png is created

  This works fine. The Agg backend work fine for me.

  I've been using the WXAgg backend interactively from a WX based
shell. So, basically I do the following:
  1) plot([1,2,3]) and the plot appears
  2) click the save icon on the displayed
  3) save as "v53WXAggPlot.jpg"
  4) No file is saved.... No errors given.

  I've also tried replacing steps 2-3 with:
savefig(d:\v53WXAggPlot.jpg"), but had the same results

  So, decided to try idle -n with the TkAgg backend (interactive mode
= On).
  1) plot([1,2,3]), and the plot appears
  3) click the save icon on the displayed plot
  4) saved as "v53TkAggPlot.png"
  5) It saved!

  I've also tried replacing steps 3-4 with:
savefig("d:\v53TkAggPlot2.jpg"), and it saved too!

  So, finally I decided to go back to matplotlib 0.51 using a wx based
shell w/the WX backend with interactive mode Off ( interactive wouldn't work
for me in V0.51).
  1) plot([1,2,3])
  2) show() and the plot appears
  3) click the save icon on the displayed plot
  4) saved as "v51WXPlot.jpg"
  5) It saved!

  Could this be an issue isolated to the WXAgg backend in V0.51-3?
