Thanks Darkfoil & Nickydude !
The v2.0 seems to be working fine on Vista for me.
I hope you Vista guys remembered to right click as select "Run As Administrator" when you ran the installation exe, since it installs in the program files.
This thing is really fantastic!
I love the texture mixer, and the layout is nice too.
Very NICE!!!
Thanks again.
Edit
I ran into one small problem while trying to use the texture mixer.
The files created would not load again. (gave an error)
While examining the files I noticed they were missing their file extensions.
So, I typed the proper extension onto the filename and it worked fine.
Now, when I type in the filename as I'm saving, instead of typing "testwall" I type the whole thing... "testwall.jpg" , and it works fine.
I don't know if this is a Vista thing or not but it was easy enough to work around.
Thanks again for a really neat program.
