Sorry I was of no use, I must say your description of the Gnat/touchscreen brought to mind the old, oft heard song of long ago, "The sexual Life of a Camel". Now, I'm not sure why, but your description just makes me think of that song. I'll not get any sleep tonight now, I can't stop chuckling
. Maybe something to do with the line - The sphinx's inscrutable orifice ?
Goodnight Danny
