Well I manged to download it before, or so it appears to me at least, their website crashed / was taken off-line.
True it has the 40D capability at last but, according to the forum, only with a very limited number of lenses at the moment. It looks like it covers my 17-85mm workhorse though, so that's good (for me at least

).
The interface is different from the 4.x version but not hugely so, it shouldn't take too long to get the hang of it if you're familiar with the previous version. Have to accept it could be a little daunting if you've not used it before.
I'm sitting here waiting for my first test batch to cook and one thing I will say is that it's not any faster than the old version, in fact it might actually be slower! This is slightly disappointing as this version is supposedly a re-write from the ground up.
The speed may be down to my PC, I'll check the "minimum specs" when I can get back on their site. I'm running a dual core 3GHz P4 with 2GB RAM and I suspect it's the RAM that may be the issue. Unfortunately my motherboard won't take more than 2GB so it looks like I might have to upgrade

and I've been trying to put that off as the PC works fine with everything else.
The results will be interesting because I'm off with conjunctivitis in both eyes! (on top of ear, throat and chest infections!) so my eyesight is slightly compromised at the moment
