Required Form Fields Not Validating

[#1]

I demo'd a fill and print form yesterday and was quite embarrassed.

The only logic in the form so far is that some fields are required, and display a text message if you leave the field blank.

I had the user tab off of a required field and they were able to do this without receiving any kind of a prompt.

Reader sees the fields as being required, but no key stroke could get the validation message to pop up.

This has worked on several other computers, all XP SP2, Reader V 7.

The computer it didn't work on is Windows 2000, not sure of service pack level, but IE6. Confirmed reader is at V7.

I actually just took an Acrobat class, and stumped the teacher, so both of us want the answer now!

Also posted in Reader forum, wanted to see if anyone over here had seen this happen.

Ideas?

Thanks in advance.

I have run into a similar issue. I defined a radio button group as requiring user input. I have also defined an empty message to use with the radio button group. However, as I tab off the radio button group without making any selection, no error message shows up at all.

I discovered that an earlier version of Reader was on this computer--once I uninstalled, reinstalled V7, form behaved fine.

Good Luck
