Not on the Template Editor. Not on Mission Control on a Mac. There is nothing to drag in Safari, Firefox or Chrome.
Rockettheme is probably using some kind of programming for the iFrame that is Windows browser friendly, but which does not show the drag-able corner. Here's a screenshot...
I use JCE for all editors in all my Joomla sites, but I've been working with the free Gantry framework a LOT and I do a ton of editing via the editor window for the Templates. I can set the re-size on the editor windows for Articles and such, but this one seems stuck.
There should at least be a simple way to change this via a CSS modification to the Mission Control template. If there is a way f doing this, I'd like to know!
Sounds like a Mac issue. I'm using the the latest Mission Control template for 1.5 and I can re-size the editor.
See the screenshot. It's Chrome on a Windows 7 machine.
1.7 - and you have a point, however I found the editor in 1.5 had a bit more breathing room. Is there a simple way to change the height of that window? There's an iframe, but there are a few boxes containing it that had me a touch confused.
