1. When using free transform in cs5, text is resized, but the point size isn't increased.
So - You can have text this big and this big, but the property inspector will think both are size 20.
It's quite annoying, and changing multiple blocks of text at once, in proportion to each other, is only practical with the Ctrl+T tool.
2. The anti-aliasing is also unreliable - has that been altered?
3. This text resize bug, from my blog, is also still an issue - has that been fixed?
If so, pretty ready to upgrade!
