1) I sent an email from RC this morning and didn't include line breaks. When I check in my "Sent" folder it shows the message but it goes off the screen and it's unscrollable both in the preview and when i double click it to view the message. Word wrapping in such a situation would be great, also when writing emails you should make the textarea not horizontal scrollable.
2) You can't preview drafts. Move the message to another folder and you can preview it but not while it's in Drafts.
3) I also viewed a draft saved by RC in Outlook and they were different. Outlook showed it correctly as having text and a signature, RC only showed the signature. Maybe it was accessing an old version of the draft saved locally?
Great script! I feel I'll be using it for a long time to come. All of these bugs are minor and don't really interfere with the script itself.
EDIT: In regards to the line break problem, I'm using the default theme, not BlueTabby so the theme shouldn't be the issue unless the default theme also has the same bug.
