Adobe LiveCycle Designer 7.1 is having serious performance issues when dealing with some forms. These are fairly simple, one-page forms, around 215KiB. I am running on a Pentium D 2.8GHz with 1GiB of RAM. When trying to open the forms, LiveCycle eats up a whole CPU core and several hundred MiB of memory, and it takes on the order of 10 minutes to open. Copying a single form field and pasting it is an hour-long operation. I have already tried uninstalling and reinstalling, it had no effect. The computer is clean of viruses/spyware and is as up-to-date as I can get it. Deleting and recreating the forms is an absolute last-resort option, and at that point not using PDF at all is under consideration, so I would like to recover them if possible. The forms work fine under Adobe Reader, no performance issues. Any ideas?
