Dear Colleagues,

is there still someone who remembers some PNG export problems under
version 6.0 run on Windows systems? The following example does not write a
file, even though the message suggests some action (export as TIFF works,
btw.):

In[1]:= Export["c:/test.png", Import["ExampleData/spikey2.png"]]
Out[1]= "c:/test.png"

Reading the message but finding no file is rather unusual using
Mathematica. Looking whether the exporter PNG.exe was launched gives no
suspicious feedback:

In[2]:= Select[Links[], StringMatchQ[First[#], "*PNG.exe*"] &]
Out[2]= {LinkObject[
"\"D:\\Program Files (x86)\\Wolfram \
Research\\Mathematica\\6.0\\SystemFiles\\Converters\\Binaries\\\
Windows-x86-64\\PNG.exe\"", 5, 5]}

Interestingly, on another v 6.0 installation under Windows this PNG export
works fine!

Thanks for any hints - Ulf-Dietrich Braumann
