Opening images is really fast.
Crashed several times on my Vista laptop.
The software is good but the interface is quite messy. I bought it last year and it worked great on my XP PC but not on my Vista laptop. It crashed several times and i also lost lots of data. I've stopped using it. But i found a great and free alternative - Kestrel GX.
Overall ACDSee is a good software when it works. The developers should really work on the interface to make it more user friendly.
