Tab Ordering Slow and Ordering Bugs

I'm just trying to see if anyone else has seen these issues and if there is a way to resolve them.

I'm using LiveCycle Designer 8.2.1 to design a form. The form is 20 pages. Each page has between 8 and 100 form fields, the average probably being 20.

When I try to move the tabbing order in the Tab Order list pane by dragging and dropping an item, it takes about 14 seconds for each change to take place. I have a powerful computer with a bunch of RAM, so I don't think this is the issue. My resources are only at about 50% when I try to drag and drop a tab order.

On a side note, I used to be able to select an item in the Tab Pane, hit F2 and type in a number and the item would be re-ordered. This ordering happened in less than a second. But, now when I type in the new number and hit the enter key, it just instantly reverts back to the old number.

Thanks,

James
