I believe this started at some point after a Windows 8 update but not sure.
Every so often when I alt/tab back to DW from another app, the cursor spins and the entire editing window 'winks'... it goes into a lo-res text mode (reminiscent of ancient dos) for a second, then 'snaps' back. Takes 4-5 seconds. A minor annoyance, but it happens several times a day.
Note: I have the sleep set on my HDs and occasionally, Photoshop will 'hang' for a moment when opening a file dialogue while the drives wake up. But there are never any of the display 'winks' as in DW.
Any ideas? Haven't noticed this with any other apps.
TIA,
