discussion. For reason unclear to me, my posts to the list are held
up in some nebulous zone for many hours....

It looks like you are running in an environment where HOME is not set.
The TTFQuery file _scriptregistry.py first checks for the HOME
environment variable and tries to put the font cache there. If it
fails, it falls back on a python dir (which works well for linux and
win32 respectively). Also, make sure you are using version 0.2.6 of
TTFQuery.

So either 1) set HOME to point to where you want to font cache to go,
or 2) Edit _scriptregistry.py and manually set the registryFile
variable at the top of that script.

I understand. If you have a publicly viewable screenshot that you can
share for the screenshot page, let me know. Otherwise, just pass on
what you learn about the mechanics of getting it up and running.

Commented out line 43 in _matlab_helpers fix my issue. Is it because I don't
have any window to destroy?

Here is small example (which creates problem without commenting line 43)

from matplotlib import use
use('GD')
from matplotlib.matlab import *
bar([0,1], [0,2])
savefig('test.png', dpi=100)
close('all')

bar([0,1], [1,1])
savefig('test1.png', dpi=100)
close('all')

********************New destroy function in _matlab_helpers (Need a fix if you

    def destroy(num):
        if not GcfBase.has_fignum(num): return
        figwin = GcfBase.figs[num]

        oldQue = GcfBase._activeQue[:]
        GcfBase._activeQue = []
        for f in oldQue:
            if f != figwin: GcfBase._activeQue.append(f)

        del GcfBase.figs[num]
        #figwin.window.destroy()
    destroy = staticmethod(destroy)
