First, after installing GPO with Sibelius on my new laptop, I find that the GPO instruments sound less realistic than they did on my old laptop. They sound somehow unrefined, and non-legato. I've gone through hell to install updates, especially from that un-userfriendly Native-Instruments site, and still no improvement. Any ideas?

Second, any idea why the timpani on GPO bangs one note whenever I minimize the Sibelius screen. Whenever I do anything like open a new window or exit the sibelius screen, the timpani note bangs! What's up with this? Didn't happen on my old laptop. Updated Sibelius, no change.

I guess that's all. Thanks.
