PMView Win tries to open MP3 files? Options

[Morris]

PMView Win attempts view MP3 files, which seems to hang the system while it tries.

Situation: A couple of GIFs of CD covers in a folder with the MP3s for that CD. Open GIF in PMView by double clicking on the GIF. Page down in PMView to view the next file. When the next file is an MP3 then PMView tries to open it, hanging up the system for a long time.

And it is even worse in a subdir with an audio book: I have one where there are two 60 KB GIFs and twenty-four 20 MB MP3s. I thought the system had died.

The MP3 extension is not in PMView's list. And I can find no setting to prevent this behavior.

Is there a way to prevent this?

System:
PMView 2.14 (registered)
(also failed on earlier versions)
Windows NT WS 4.0 SP6a
Pentium III 450, 256 MB ram

Thanks
