Make sure you clean up your registry before you install Vue 5, Veritas; Like VuePro, there a few more interconnections to the OS, and any detrius from a previous installation that was removed can do icky things. Trust me. Helgard; Oh yes....the Alpha plane AVI ability would =so= rock (thinking of Mobius' Antares bridge with 'vued' consoles...). I wonder if the truly next big innovation to go into VuePro may just -be- that particle based weather system. VuePro 4 has the wind dynamic trees. It supports Python. Just adding the new lighting features wouldn't be -that- impressive...it would actually make it look more like just stealing the upgrades from Vue 5. But if they used the metablob tech to create serious wave capability, or added particles...even if it were limited to just weather features...now =that= would come across as a boon, and really make the case of the lines being different products. Now to get Vue5Mover5Cows5 reinstalled and start trying to break things....
