AFAICT, the GUI removes the PPM/PGM files for a layer when you remove
the layer from the display, or when you close the map window.

One possibility is that the close event doesn't get handled on Windows
for whatever reason.

Can you conduct some tests:

1. Start the GUI from the command prompt, display a map, then quit. 
Report any error message and whether any PPM/PGM files are left
behind.

2. Start the GUI, add some maps to the list, display them, remove some
maps from the list, check whether the PPM/PGM files are deleted as the
maps are removed.
