Active window flickering

I have seen Finder window flickering (losing focus and returning to the front rapidly and repeatedly), but not application windows.

Do you get the same issue in a new user?

New User 10.5

I have found a solution to this problem (depending on your setup it may help)...

*1. Open System Preferences*
*2. Open Flip4Mac WMV*
*3. Click on the 'Player' tab*
*4. Click the 'Reclaim' button, to reclaim playback from other players.*

Obviously this works only if you have Flip4Mac installed. I progressively went through every system preference setting making one change at a time until I happened upon this solution. I am assuming that something in the 10.5.3 update (or similar) was conflicting with Flip4Mac.

The same issue appeared here with 10.5.4 -- anybody have an idea?

I've been having the same problem.

At first it was just with Finder Windows, then it started happening in Safari, Mail, and other apps.

I tried the Flip4Mac trick, but it didn't work.

Any others having these issues?

("Active Window Flickering" is a good way to describe it. I had been having problems finding a thread because I wasn't sure how to describe the problem. Has anyone found other threads on the same topic? Maybe with a different way of describing what is happening?)

I am also having this issue and it's getting annoying. I'm glad I finally tracked down the other people who are experiencing it though!

I'd like to get a response from Apple on this. Very difficult to try and reproduce in a store as it seems to happen randomly

I have this problem for 5 months already, this annoying flickering active window problem. Sometimes it gets very bad.
4 Months ago I created a new user and deleted the preference files... and it stopped for one month. It slowly started again. FlipforMac did not solve the problem. Creating a new user again? I don't think this is a right solution. I called Apple support and they directed me to this post. Oh well...

I think I solved the problem. Here are the steps:
1. I created a new user ADMIN
2. I logged out and started a s anew user
3. I restarted computer and logged into the old user

The flickering is gone. Maybe it will come back again one day, and I will have to do this procedure all over again, or maybe someone will find a permanent solution by then.
