I'm using Adobe InDesign CS 5.5 on Windows 7 64 bit with 8GB RAM and Intel Core i7 CPU. when I open a document and press "ALT" key and Scroll my mouse for Zoom-In or Zoom-Out then Adobe InDesign is slow and can't doing this task properly. How can I track this problem?
Is that the only time InDesign CS 5.5 slows down?
If so, you might experiment with other ways of zooming in and out:
No, Move between documents, Save documents and...are slow.
