Normally, when you hold down the spacebar you can use the hand tool to drag around the document... and use Ctrl and Alt for zooming... but it doesn't work.
When I try to hold it nothing happens and it is really bugging me... Trashing and resetting the preferences folder didn't worked at all.
Can anyone help me?
Look at the side column to the right of this box called "More like this". And note the suggestions there.
This problem comes up frequently and the answer is usually that some other application/programme is interfering.
It is solved without reason... I just did a update again and it seemed being fixed...
Be sure you don't have the Text Tool active and an insertion point active in a text object. (Easy to do accidently.)
