Scaling is fine and acceptable in some cases, like for slaves when 6 boxing lotro, and for scouts in eve. I am aware of the issues in eve where mouse clicks in a scaled client will not line up properly. I'd also assume the same to be true for any other client that can not be set to an arbitrary size.

If ISBoxer is confirmed to be able to scale the clients down to an arbitrary size, I'll certainly give the trial a try.

Any other software that can scale the clients?
