Does anyone know why this could be happening? I updated Grid again yesterday and am seeing the same thing (unable to select anything to display in the center text 2 position). It's very possibly an option I'm missing. Any ideas?
Did you enable center text 2 yet? Its hidden somewhere in the advanced options.
I'm going to remove the text 2 indicator from the menu if you can't find Grid -> Frame -> Advanced -> Enable Center Text 2 Indicator.
Now it's in the FAQ.
For those of you having the problem where you can't click on random units, I suggest trying to find which other addon is causing it.
My apologies, I wasn't aware of the option to enable it as it was enabled the first time I installed Grid. I'll look at that after work, and thanks for the response.
