I typed *.png
in the File name field to see if the All Formats file type selector was messed up. This did have the effect of at least listing the files I was looking for.
When I selected the file I wanted and clicked the [i]Open[i] button, I just got a message saying:
The picture it not a correct imagefile
(yes, the spelling is correct).
My browser (Firefox 2, IE 7) and the Windows picture viewer (in Windows XP) are able to open it perfectly. What gives?
