issues with Adobe forms

[jwaite]

I created a form (from a PDF'ed Word document) in Adobe 5.0 on an Office 2000 Professional platform and I emailed it to coworkers running XP and Office 2003. When they click on the form fields to enter information, these up/down arrows appear in the field while they're typing and, once they tab to another field a small black box with a + sign remains at the end of the field, even if the text did not take up the entire space. They show in the printed document as well. It also makes any text entered look as if it is superscript - the text is several points above the underline (the underline was created as part of the field, not in the original Word document). Of course, on my machine these arrows and + signs don't appear and the text is typed exactly on the line. This seems like an XP issue, only because the arrows have that rounded XP look... though they've also been experiencing some similar troubles with Word 2003. Anyone have a clue what these signs are and how to remove them? Are there issues with Adobe 5.0 and XP or 2003?

Any help would be appreciated... thanks in advance!
