Thanks for posting in Microsoft TechNet Forum.
For further troubleshooting, may I ask some questions:
1.What is the edition of Communicator?
2.Does this issue occur with other communicating applications such as Windows Live Messenger? Have you tried communicate with another person and see if the issue occurs?
3.Are there any other applications running while you use communicator? There may be conflicts between communicator and other applications that infects the desktop UI.
BTW, please also refer to Office Communicator 2007 Solution Center for method.
I have the same "osicillation". I get it sometimes when I am viewing video training via CBTnuggets website. This is through the newest IE. It also happened before the upgrage. I found that if I click the taskbar while it is happening it stops.
Other applications have caused this as well, but I don't recall which ones cause it.
running intel DC-2.0Ghz
Intel intergrated graphics not sure the model.
3.0G DDR2 RAM
When I do a chat in e.g. Communicator and a person responds, why do the taskbar blink when I already have the window active? It's very annoying.
I have this same thing occurr with any windows based screen is displayed (Internet Explorer 8 or Windows Explorer). Very annoying and I cant make it stop. I did not have this problem with Vista on this machine.
Do you enable Aero Glass on your computer? Please try to set to Windows Classic theme and see if the issue occurs. If it is the case, you'd better run Aero troubleshooter to automatically detect the problem and fix it.
Sometimes this behavior may occur if either of the following is true:
1. You open a window and it is initializing at the same time you switch to another window. While the previous window is initialized completely, it blinks to remind you that it has been opened.
2. Two processes are written to system memory at the same time with the same trigger.
3. The virtual memory is limited.
To troubleshoot this kind of conflict, I would like to propose the following suggestions:
1. Enlarge virtual memory.
1) Press Win +Break and click Advanced System Settings
2) Click Advanced and click Settings under Performance.
3) Click Advanced and click Change under Virtual memory.
4) Uncheck Automatically manage paging file size for all drives.
5) Check Custom size and type numbers for Initial Size and Maximum size (I prefer to use 3000)
2. Run Disk Cleanup utility to delete redundant system files.
3. Run sfc /scannow to automatically scan the whole system files and fix corrupted ones.
I also have this problem. IE v8.0.7600 and it blinks on and off constantly. 4 GB RAM. Virtual memory = 3062. It seems random ... sometimes the whole page would blink and sometimes it the advertising on the side. Recent websites were yahoo.com, sportsline.com.
