Copying the file to the shared applications area worked for me. That is how 
I moved it off of my
laptop onto the linux box. Oh well, at least you got it working. You are 
right it does need an
undo function. A refresh function that would erase all the markup would be 
good too. Maybe one
that would erase just the color you were using and no others would be 
useful. Here we go !
