I sorta wish I had you're problem. I rather have the old dock indicators, which are easier to see. First time I've seen it in the forums. It's most people complaining about the dock indicators being hard to see in ML.
Thanks Richard. If only I knew where the ML Install app went?
Looks like it deleted itself?
Anyway, I downloaded/installed over again. After boot, there was no way to have a system sound. Both of my users were muted.
So I downloaded/installed a third time. Until now, all seems OK. But I'm not happy with my MBP anymore. Does it "just work" by luck now?
The 2nd lower layer of indicators is also visible in Lion. It's the reflection of the upper indicator. The only reason why it's noticable on your config is because I think the "plate" of the doch has become a bit thicker (I think, I'm not running Mountain Lion).
Why are you not happy with your MBP? Because of this little dock indicator "issue"?
