I did some debugging on my out-of-range-but-healable-player issue and I discovered the following.

GridRange.lua have the function:
local function checkRange40(unit)
    return UnitInRange(unit)
end

However UnitInRange(unit) isn't really set to 40y. Instead is set to 38y. Don't ask me why, but in wow 3.3.0 is it in that way.

The solution is straightforward:
GridRange.lua, line 58:
change "local function checkRange40(unit)" to "local function checkRange38(unit)" (just 'cuz I love to be consistent)

and
GridRange.lua, line 70:
change "addRange(40, checkRange40)" to addRange(38, checkRange38)

After this change the range for 40y will be correctly set by spells in your spellbook, so if a player will be grayed out it's cuz he/she is *really* out of range.

Cheers,
