Error best seating an empty Package

Hi all, apologies if this has been brought up already, but we've found a consistent way of crashing Tessitura by trying to Best Seat a Package before select a Price Type. Has anyone else experienced this? Here are the steps:

- Add a Package, select performances within the package.

- Click Best Seat before selecting a Price Type, and on our systems Tessitura consistently locks up with no error message, and you need to CTRL-ALT-DELETE, end task, and reopen the application.

If a Price Type is selected and no Quantity is selected, it won't best seat, but Tessitura doesn't lock up. If a Price Type is selected and Quantity is selected correctly, it works perfectly of course.

Thanks!
