I have a 14 page LiveCycle 7.1 document that works perfectly in Acrobat 7.0.8, however after downloading the Acrobat 8 Pro trial and opening the same document in Acrobat 8 Pro the document is a bit slow. When I attempt to fill out the form it now takes 2 seconds to tab between each form field. After hitting the tab key Acrobat spikes the CPU to 100% for 2 seconds. Bummer, hope Reader 8.0 won't have this problem when it's released, but I'm sure it will. Someone broke something. I did notice that if I don't use the tab key but instead simply click on each field in the form it works perfectly fine without this issue. Something is terribly wrong/inefficient with the code that's used to determine which field to tab to next.
One other thing that I noticed that appears to be broken is the print button on the main data entry page on this document calls the following code:
// Print.
xfa.host.print(1, "1", (xfa.host.numPages - 1).toString(), 0, 1, 0, 0, 0);
In Acrobat Reader 7 this code causes only page 2 to the end of the document to be printed. However in Acrobat 8 Pro this doesn't work as expected. Instead of only printing page 2 to the end of the document it prints the entire document.
Neither of these issues are good. Any suggestions?
