I have had a similar problem (though not as vast). I just tried Smallpiper's suggestion and it didn't work; in my old WordPerfect format the "paste" tool isn't available if what I've highlighted is not a recognized document (I used Noteworthy Composer). Rats! It was a great idea!
(When my son takes this computer to college in a few years (with upgrades) I'm getting me a real computer!)
