Ok. Duplicating exact function then? Meaning the EXE has all that the Lua
script has, plus commandline processing? I ask because the EXE works as usual
if I hide the script from it, suggesting it's not using it, at least not as I
usually call it.

Didn't work, but a clue was a lack of quotes round the filepath after the -c
switch in the DisplayOutput window. So I went to frame:Connect(ID_RUN... and
changed a line as follows:
local cmd = '"'..programName..'"
'..console..openDocuments[id].filePath
to
local cmd = '"'..programName..'"
'..console.."\""..openDocuments[id].filePath.."\""
which works.
The wxLua console window pops up but is empty, and the script loads and the
frame shows. Those quotes are vital when the file path is passed to
os.execute(), at least in MSW they are...

Thanks, that one's nice, no flicker of any kind. I'm having trouble integrating
it into my main script but I'll post once I sort out the confusion. I guess
there's no problem with two OnPaint() functions? So long as their names are
different, one for the PANEL painting, one for the layer vector stuff..
