|Dell Studio laptop. Windows Vista.|
Flickering screens constantly popping up when on Hotmail (and Google) - can often be closed by pressing F12, but recur frequently. They have the effect of disabling the screen. Their toolbar often begins with 'Elements' or 'Developer Tools'. 'F12' sometimes appears on Toolbar.
Also, in Word, 'Save As' menu constantly pops up unbidden, and often cannot be closed down, even by pressing Enter, Save, Cancel or clicking on the red cross.
Have run McAfee Virus Scan and Malware Bytes - says all clear.
Suspected my keyboard and pad, but same thing happens when I use auxillary keyboard and mouse.
Any suggestions welcome!
