Well, it's been a long time since I installed it, but I remember the first 3 or 4 times I tried to install it, it didn't take. Finally, I had an icon and was able to click the "options" button and told it to run in compatibility mode (or something similar. Sorry i don't remember the exact details), but it DOES work perfectly once you get in installed and set for compatibility mode.
Yes, TINT is still a bit quirky. I had it running perfectly too until TS3 came out with an update and made some ofthe necessary TINT plugins nonfunctional.
For TS3, your only other option right now is PlayClaw (
http://www.playclaw.com ). It's free for a 14 day trial and worked really well for me, but the 29.99 price tag for the full version seemed a bit steep at the time...especially considering it offers about the same functionality TINT did (when it was still working).
So, right now, I'm still in TS2 preferred mode WITH TSO working as it should.
