Are you using a Magic Mouse? Or inadvertently using the scroll on the mouse while holding a modifier key?
Thanks for your reply.
No Magic Mouse here.
However, I do usew a Wacom tablet which has new drivers since a few days.
Could that be.....?
Or is it time to trash the ID prefs?
Can the wacom tablet zoom in and out of InDesign?
It could but it is not configured to do so. I am not toching the
touch/scroll wheel on the tablet.
I switch from page to page using the keyboard with Alt-Page Up/Down so at
that time the pen in my hand is too far away from the tablet to be able to
interact and I am not touching anything else but the keyboard. The buttons
on the pen are disabled.
I'll downgrade the Wacom driver tomorrow, see if it helps. I will also try
to work with a mouse for a while to see if that helps.
Apparently it is the latest Wacom driver which is causing this odd
I downgraded the drivers to the previous version and all is fine again.
