There are two diagonal lines in the lower right corner which I can actually 'grab' and drag to enlarge/shrink the size of any message box, including tree-mail. The size change does not show in the preview or in the finished message.

Has it been there forever or am I just unobservant??

I think it is fairly new. I noticed it a couple of weeks ago.

LOL, it took me a few minutes to realize what you were referring to; I can't recall how long ago I first noticed and began using it but I'm pretty sure it's been a long time.

I only see it on my laptop (Windows) not IPhone or IPad. Never noticed it before.

Never noticed it. Guess sometimes things have to be pointed out to be noticed.

I only use a laptop.

Aww, Thanks Sue! We have a large Blue Plumbago shrub growing beneath a big live oak tree in our front yard and I love the blue flowers.

That resize thing is a feature in your browser and isn't a part of the site here. I know on my browser I've had it for many years.

Ha! I suspected that! I swear every time I turn around Firefox has changes. There are so many people working on it and it seems like just about anyone can work on it. In fact, I find it a little scary every time I see Firefox "updating", which seems pretty often now days.

Textboxes have been resizable in many browsers for ages. Firefox certainly had it when I started using this site years ago, but they have made some UI changes this year and so it's a little more obvious than it used to be.

Firefox is on a monthly update schedule, excluding security bugfixes which can happen weekly.
