I find this happens quite alot. I go to launch an application, say from the dock, and it appears to be doing the right things, but only ends up show up in the finder window as "open" , but not actually open. I have to then go and find the file/doc i want to open.
What I'm saying is, it appears in the top finder window as the application name as per normal. But doesn't actually bring the app to the front.
clear as mud.
P.S my mates macbook pro is doing the same thing.
new 2.4 macbook white.
