JBARLEY  It's a simple matter to put the old icon back.

Just ctrl+click on the caffeine app and select "show package contents- Contents - Resources".

Here's where you'll find the 2 icons, just replace them with the 2 from the earlier version.

JBARLEY  Unlike some folks, I'll not bitch about the cost, I'm just glad for the timely upgrade to an excellent and versatile program.

My moneys on the way.

Keep up the great work guys.

JBARLEY  It appears, at least on my MBP, that Leopard has broke xPad.

It will load and run, but when I start selecting messages from the list in the drawer, things begin to fall apart.

Most evident is, as I select each title, it disappears from the list, annoying to say the least.
