This is exactly the same problem that was reported for a windows pc. in 2005. vis:
On all of my applications the screen 'blinks' every 10
seconds and whatever drop-down menu I'm in will close. This is very
annoying because on a long drop-down list it will pop closed before I'm done
selecting and I have to try and beat the clock to get to where I need to
click before it closes again.
In Apple mail it's really difficult to type an email without going back to correct missing text caused by the 'blink'
This only applies to applications. The desktop is fine!
