pb1711: why the hell try and fix something that's not broken?
Prior to this "fix" ( transparent avatar option) there was a bug where the avatar would not go transparent/translucent if you had just previously done a replay of your approach shot to the green. So instead of fixing that problem wgt added a new feature/option to make the avatar always transparent via an option.
I've submitted several problem reports when the avatar was not transparent/translucent when it should have been, so I'm sure wgt knows about this newly introduced problem.
