I don't have windows vista and finally there is good news! After about 5-6 weeks of waiting Don has sent me the terrain! All is going well and I expect the map should be finished in about a month or so.
You'll need to make a custom unit based off Fountain of Life. Then add the abilities Life Regeneration Aura (Neutral) and Mana Regeneration Aura (Neutral). Make sure the abilities are custom so you can edit them.
Ok so here are three of my heroes so far that are going to be in my hero arena.

This should stop the units stopping randomly. Edit what you need.
I found that after the ability is cast the dummy unit that is created at the target location shows on the minimap as a white dot. You may want to fix that.
