TypeError: Surface.write_to_png takes one argument which must be a filename (str), file object, or a file-like object which has a "write" method (like StringIO)

This is a bit strange. The error is triggered because somehow the string you are using for the file name is type unicode instead of type string. Not sure how that could have happened. I'll add a conversion in these cases, but will also try to find the root cause, i.e., where the unicode conversion is happening.

if type(file_name) == unicode:

img_surface.write_to_png(str(file_name.encode('ascii', 'replace')))

else:

img_surface.write_to_png(str(file_name))

fixed in v139, although the root cause is still somewhat of a mystery.

[tonyforster]

works ok in v139

FWIW green text boxes are all type unicode and purple number boxes are all type float

[tonyforster]

I wasn't quite right there, the text block on the pallette is type string but it becomes type unicode when edited
