Thanks I use Windows 7 64 bit.
I have seen reference to alpha channel but don't know that they are. Could you
explain what an alpha channel is and is there a method of adding a layer which
is not an alpha channel?

Maybe I can EXPORT to another format then import into Paint Shop Pro convert and
save?
