This is done in the bindings-cache.wtf file. If there's a soultion another place, please let me know.
I would like to use MOVEANDSTEER on my right mouse button (bind BUTTON2 MOVEANDSTEER), and then (with "Ice Floes" on me) cast a channeled spell, say "Ring of Frost". So I hold down mouse butoon 2 happely running around, press mouse button 5 and the targeter comes up. THEN I hit mouse button 1 to drop the spell down, but... Hitting mouse button 1 canceles MOVEANDSTEER om mouse button 2 and I have to realease it an click it again. Not a big thing? Well, makes casting while moving a lot harder than it should be.
Any solutions would be greatly apreciated.
ps
I'm guessing WTF doesn't stand for What The Fuck. Any idea what it stands for?
