The only extant version of Arcanum (it would seem), maintained by someone-or-other at http://wow-arcanum.c.la/ , breaks at level 65.

Before TBC, a huge portion of Mages used Arcanum or Cyrolysis to save nearly two bars worth of utility buttons. What are you using now?

There's a post 65 version of Cryolysis I think (http://www.curse-gaming.com/en/files...3425/cryolysis) but I get a green square where my water icon should be. All the functionality still works.

Cryolysis still works for me. The "original" author updated it, after there was some dispute about ownership, resulting in slow updates (for values of "slow" that include "none at all") for a while. It's even got Shat and silvermoon portals/teleports. I'll hit 65 tonight so I dunno if the water will still work at that point. It doesn't seem to keybind properly for the mount button, but I solved that by tossing my mount on a spare bar and binding a key that way.

What I'd really like is a working TheoryCraft!

Yeah the version I was using started throwing errors when I hit 65, and the new portal icons weren't showing. I downloaded a newer version and the portals show up and work, it's just that annoying green square for water. Maybe I'll try redownloading.

I've just ended up adding another bar since I've been 70. I really wish they would update Cryolysis because well... it just saves so much room. As for now this extra is going to keep eating up my screen space.

Edit:

Never mind, I found one http://www.wedownbosses.com/cryo/CryolysisLenwe1.04.zip

Yeah I was gonna post that for you but it seems you found it.

Does your water button not work? Like the image is there fine, but none of the left/middle/right click functionality works.

I like the idea of a show/hide key for stuff I don't need quickly, but I use the mana gems and slow fall on cryolysis in emergencies, not to mention the food/drink convience functions.

Also I hate visible bars:

Everything is functioning correctly for me though I have to add my own little Molten Armor button around the sphere as it's not implemented yet.

(only screen shot I currently have uploaded, you can see what I did for Molten Armor)

The new Arcanum is good, actually. I don't think it has the highest rank food/water by default, but it's trivial to fill in the blanks in the localization file.
