Excellent. Since you already have a copy function, adding support for
formats to allow direct paste into other windows programs would be
useful too, though I don't know if there are enough other windows users
to make it worth the effort.

Thanks, that was just the help I needed, though entering "182 x 5964" as
the size generated a 3d table with 0 entries in the 2nd dimension. I soon
twigged though.

I might try that later, but I have exported the single table and imported
into Excel so now I can extract whatever I need from there, or even link
to it as an external database and pull any single spectrum with a query.

Thanks for the assistance.

Merry Christmas
