Scratch 2.0 Paint Editor is awful.
Um… Have you tried dragging the corner of the text box? Or any shape? Or clicking the flip button? Or copying and pasting? In the new scratch there is no scale option, no flip option, no import option, and you can only use small text.
I don't think any of the things you said is an issue. Maybe you don't know about these features, or your computer doesn't like to cooperate.
There should be an instructional manual, but they're still working on the editor overall. Another reason why the ST should have delayed the release…
