All of it, except for command line processing.

It is probably failing in the function "OpenFile(event)" or io.open()
in LoadFile() in editor.wx.lua. As you can see, there's no special
filename processing going on. Can you open the file if you hardcode
the path for io.open() in LoadFile()?

Yes the static bitmap flickers. Why don't you draw it yourself like this?
function Main()
FRAME=wx.wxFrame(wx.NULL,-1,"")
FRAME:CreateStatusBar() FRAME:SetStatusText(" ")
LAYER=wx.wxPanel(FRAME,-1) PANEL=wx.wxPanel(FRAME,-1)
--CHART=wx.wxStaticBitmap(PANEL,-1)
FRAME:SetSize(800,600) FRAME:Centre()
BITMAP=wx.wxBitmap("image.jpg")
BX,BY,OX,OY,PX,PY=BITMAP:GetWidth(),BITMAP:GetHeight(),0,0,0,0
--CHART:SetBitmap(BITMAP)
FRAME:Connect(wx.wxEVT_SIZE,OnSize)
LAYER:Connect(wx.wxEVT_LEFT_DOWN,function(E)
PX,PY=OX-E:GetX(),OY-E:GetY() end)
LAYER:Connect(wx.wxEVT_MOTION,OnMotion)
LAYER:Connect(wx.wxEVT_ERASE_BACKGROUND,function() end)
PANEL:Connect(wx.wxEVT_ERASE_BACKGROUND,function() end) --Either of
these ought to stop flicker but don't.
--CHART:Connect(wx.wxEVT_ERASE_BACKGROUND,function() end) --Neither
of them are needed in earlier wxLua anyway.
PANEL:Connect(wx.wxEVT_PAINT,OnPaint)
FRAME:Show(true)
end
function OnPaint(E)
local pdc = wx.wxPaintDC(E:GetEventObject():DynamicCast("wxWindow"))
pdc:DrawBitmap(BITMAP, OX, OY, false)
pdc:delete()
end
function OnSize(E)
CX,CY=FRAME:GetClientSizeWH() PANEL:SetClientSize(CX,CY)
LAYER:SetClientSize(CX,CY) CX,CY=CX-BX,CY-BY
if OX<CX then OX=CX end if OY<CY then OY=CY end LAYER:Refresh()
PANEL:Refresh()
end
function OnMotion(E)
if E:LeftIsDown() then
OX,OY=PX+E:GetX(),PY+E:GetY()
if OX>0 then OX=0 end if OY>0 then OY=0 end if OX<CX then
OX=CX end if OY<CY then OY=CY end
--CHART:Move(OX,OY)
PANEL:Refresh()
end
end
Main()
