Did this the other day (god knows why I've done it twice in one week - I have this laptop long enough!!!) and managed to close explorer and re-open a new one and it was fine. This time I've even shutdown and restarted and it's still a problem!!
Basically, I went to press control and page up but obviously hit the wrong key. Now explorer takes up the whole screen and there is no tool bar at the bottom or top of the screen, they only appear when I hover in that area.
HELP.....it's driving me mad!!!
TIA
