perhaps I found a bug, perhaps I don't know enough:

I created a 4x4 pixel gif, one color monochrome , just blue, 37byte
(see attachement).
Then I tried to save this gif as png (standard options)

The result is a corrupted png and the following entry in popuplog.os2:

Yes this is a bug. It turns out that saving any image with only 1 color (regardless or size) as PNG causes PMView to crash (OS/2) or generate a bad file (Windows).

This bug will be fixed in v3.23
