LOL: Neither of these are bugs. They are both deliberate effects of treeform - check the documentation. Alt-drag is intended as an alternate way to add movement lines via shortcut. I hope this helps. However, if anyone has a reason to hate this feature a lot - let me know why and I might change it.
Oh man... another one I cannot reproduce. I'm going to have to add these to my list of known bugs and just live with them. It will be at least 2 years before I can afford a 64 bit computer.
This bug will happen with some fonts when you select the entire text to be superscripted. I don't see any value in fixing this bug since it's really easy to just use a smaller font size to get the intended effect.
