I've tried two different OTA music widgets.
First:
http://spring.jobjol.nl/spring/lua-scri ... sic-widget
It wouldn't show up in the F11 menu. No music

I deleted the files.
Then:
http://www.springfiles.com/spring/lua-s ... player-adv
Same thing. Can't find a place to enable.
I also installed a non-music widget. unit_z_selector.lua - but it doesn't show up in the list either.
To be clear, I extract the zip, place the .lua in
C:\Program Files (x86)\Spring\LuaUI\Widgets
And when appropriate, place supporting files in
C:\Program Files (x86)\Spring\LuaUI\music
But I am not given the option to enable/disable new widgets in the F11 menu.
Any advice?
I'm running W7 64 bit. BA 7.2. Latest version of Spring. 250GTS. 8GB. Quad-core. Etc.
