I think that this discussion misses one of the big issues with no psd thumbnails in Vista OS. If you use Lightroom 2 to import images that are on a drive you cannot see what the psd images are without leaving and using bridge or a better program like Irfanview. Talk about an albatross around your workflow neck.
Now I'm excited. FINALLY! Someone is actually doing something about the icon in the .psd format.
It's much easier to view your icons in explorer than to launch Bridge. I don't care how fast Bridge is,
it's a program that needs to be started vs. just looking at the icon in explorer.
You still have to open explorer in order to view and wait for it to populate. Just like opening bridge up by itself, view and pick what you want, or just double click on it and it opens in CS4 64 bit or 32 bit whatever you choose.
Still it is nice someone is working on the explorer part though and it working in 64 bit more will be sweeter.
I checked their website and it does not Vista 64 bit. Vista64.com has a link to xyplorer (for example) and it works in windows Vista/7 64 bit, does not replace explorer but works along side. $16.00 cheaper too. Not that I am in the market for such software. Just you sparked my interest to research further. There are a few others out there too.
