Woah! In 3.0.3 the following forms and modules are not used anywhere, they just exist in the folder for the client...

frmInventory.frm
frmInventrory.frx
frmGetData.frm
frmGetData.frx
modBitmap.bas
modCatalyst.bas
modTCP.bas

and the server...
modCatalyst.bas
modTCP.bas

is there any reason these are there?
