Mind you, I am really enjoying Lion EXCEPT for Mission Control.
Expose was so much better for me.
It always showed me ALL my Windows, even those minimized into my Dock.
Mission Control needs to fix this "yesterday"
The Only two bugs I was seeing were:
iChat would not auto login to my account. It always started "disconnected", to which I then had to select "available", to actually connect/login.
This update took my iChat from v6.0 (925) to v6.0 (927)
and all is working perfect. So, NOW FIXED.
I was unable to access all my Shared Files, on the Primary iMac, from the three other Macs in my home network. The primary iMac has 6 hard drives connected to it, with all my Media. Post this update, ALL FIXED.
So, ...now I'm just waiting for Apple to fix Mission Control, so it incorporates ALL Expose functionality.
