I have created JavaScript for number linking, if I click a number in fig it will go to the corresponding explanation. This was developed using acrobat 8. But in adobe 11 it is very slow to execute. Previous when I execute the script it was taking 2 sec for the file. But for the adobe 11 it is taking 2 min for each file. It is JavaScript problem in Adobe Acrobat XI Pro??
