G5/2.0ghz/dual/1gigRAM/OSX4/QuarkXpressPassport6/Acrobat Reader 7

Does anyone know why I cannot COPY corrections noted in correction memos in my client's Acrobate 7 pdf doents, then paste them into my original QuakrXpress Passport 6 doent?

It all used to work before I upgraded to TIGER?

I can copy and paste within QuarkXpressPassport 6, no problem, but to copy inside Acrobate 7 pdf then past in QP6 won't work anymore.
