Good for awhile, now...

Last week it worked just fine. Now it’s replacing quotation marks as ". There’s no option to update Trillian, and I can’t find anything in settings or preferences that can correct this random issue. I’ve had Trillian for well over a year since AIM decided to stop working on my MAC and I can’t even download AIM again.

Nothing but issues the past few days

Half of my contacts are showing up off line when they are online. I tried restarting my computer and the issue is still there.

And on another less importnant note, why does the Mac version of Trillian no where near the PC version? I want the emoticons and a more modern looking software.

Okay, new version, finally!

I’m changing my 1 start to a 4 in the hopes that this version will be more stable (it has to be). If it proves to be so, I’ll change my rating to a 5.
