Acrobat Pro 9 & 10 crash when changing read order

Question

I have a calendar I have been making in Indesign for years with no changes other than the entries.  After I export to PDF, I use the read order tools to arrange the read order for a blind client and calendars cant be read normally without giving it the order.  As of several months ago, when I go to rearrange the readorder, it will crash.  It doesnt do it to every change to the order I make, just certain ones, and those certain ones change on me each month.  Im clueless why this is and because of it, I havent been able to properly make a PDF for this blind client without the calendar reading completely out of order.  What could be causing this????

Answer 1

Your issue may not be related to a difference between v8 and 9.
I have not had this problem on my computers, but a coworker had this issue. For many documents that others were able to open and scroll through without issue, his computer was freezing and unfreezing.  IT determined his graphics capabilities were not able to keep up with the requirements of working with larger documents and gave his computer a RAM upgrade and a new graphics card. Particularly during scrolling, higher demands are made on the computer to graphically render and re-render page content. Documents giving him problems before became a non-issue.
A new graphics card is obviously a $$$ solution, but you might want to check to see if your RAM meets the minimum requirements and check to see if there are any program updates (Help > Check for Updates).
I have had an issue of pdfs freezing, but not specifically in the table of contents areas. If your document has pages with images that have an unusually high number of layers, it may affect the ability to work effectively in the document.
