Highlight unit not working?

[Weasel]

Ok, so it isn't working at all for me, I had the cav unit by itself and in a stack, tried Ctl-4 and nothing; in fact CTL *** doesn't work for any of them. I am using steam version 1.11, is that what you have? Also are you using the default WITE config or changed, I am using a changed one with different fonts because default over writes each other.
