Powerpoint Mobile and Resco Explorer

[psyche]

Here's a pickle...

Just playing with my new x51v - after upgrading from the x50v.

.ppt files will not open in Resco Explorer. When I open them, it just goes the Powerpoint Mobile File Screen, not the presentation itself.

Why is this a problem? I can only use the files in My Documents - not anywhere else (and I like to keep those files somewhere else, or in subdirectories!)

The strange thing?

File Explorer (as in the built-in Windows one) works just fine - the presentation opens without a hitch...

Anyone have a solution?
