for the first problem, yes I know about it. but I have no idea why it happens. if you cancel the dialog with the cancel button, then you can return no problem. but if you cancel by clicking outside the dialog, then you get what you describe.

However, I started last night, to completely restructure the whole application using what I've learned about Python so far to try and do a vaguely sane architecture rather than the monolithic app it is today. As part of that I am hoping to enable multiple account support, so I will be totally changing that dialog before I release the next version anyway.

as for the escape sequences, I think I fix some, but perhaps not all. part of the issue is using pango for markup which is html like itself. at some point I may revisit that logic and see what I can do.
