OK... that would kinda explain this line in the menu .xml file...

<spu force="yes" start="00:00:00.00"
image="$PATH/ChemTest4_menu0_bg_15cols.png"
highlight="$PATH/ChemTest4_menu0_bg_active_out_15cols.png"

...iff the menu0_bg_15cols image was *not* an overlay.

Since spumux is evidently treating it as an overlay, yet as used by
previous DeVeDe releases it was presumably *not* so doing, perhaps I should
be diffing a few versions of DeVeDe source-files to discover what the
difference is, & hopefully a reason for it?
