Trillian is what I use too, but the free version, I love it, except it doesn't like my yahoo connection but all the rest work great and only have to log into one thing in the morning. Freckled
transparency is something i liked in trillian too but I dont think you even have it in the pro version
That was the first thing I noticed when I started up the pro version but it might be there somewhere in the options, just havent had time to look about for it.
Yahoo has problems with trillian, did you get the updated DLL file which you had to download?
I think that was meant to fix connection problems, I never use yahoo so not sure about it
