Let me sprinkle a bit of computer wisdom for those frustrated.

First a major O/S upgrade will always result in incompatiblity with any software, so that is why it is always recommended that you check and make sure your software is going to work with the latest software, before you upgrade.

Developers spend a lot of time and effort making sure their software works on current O/S.  Unfortunately there is no magic wand or crystal ball that will let them predict how the software will behave with a future O/S, best efforts are made to stick with standards.

The above statement is true with any O/S not just Lion.  Not all developers have access to pre-release copies of an upcoming O/S to ensure nothing is going to break.

In this Case the O/S in question is Lion and the problems are not isolated to Bryce, all you have to do is read on tech sites and blogs and some even recommend that you do not upgrade to Lion because of all the things that it breaks. Apple is known to release Software or O/S with major changes that causes incompatibility with current software, this is a known fact and you can read about it everywhere. 

I dont work for Daz and I'm not affiliated with them, but we need to be level headed and not jump to conclusions when their products start crashing on an O/S that was released, a couple of weeks ago.
