Thanks, but I'm still at a loss. Maybe you can spot something. Here are my relevant panel config changes (plus title added):

[Window01]
...
ident=11001
gauge00=animation!icons,0,0,72,96
gauge01=..\..\CS_L-1011-1\panel\V-One!v1_Icon, 0, 96, 48, 32

[Window06]
...
ident=10050
gauge00=..\..\CS_L-1011-1\panel\V-One!DataCard, 0,0,188,252

[VCockpit01]
...
gauge21=../../CS_L-1011-1/panel/civa!general,1,1
gauge22=update!main, 0, 0, 1, 1
gauge23=..\..\CS_L-1011-1\panel\V-One!V-One,  0,0,1,1
gauge24=..\..\CS_L-1011-1\panel\V-One!altcallouts_CS_L-1011,  0,0,1,1


The only changes from the readme are adding -1 where necessary to L1011 to reflect the changed folder. Otherwise just copy-and-paste. Everything works fine except for not finding the SimIcon additions. I get a ding sound check on the V-One panel, everything is calculated and displayed properly, and the callouts happen as expected.
