We have fillable forms and when employees open them they can type in but as soon as they tab to the next field you can't see text in previous field unless you click back into that field with your mouse. Then when you click on print it prints the form out with no text in the field. This form can be opened and filled in if the staff member has adobe pro of nuance but not in the new reader.
Can you post a sample form somewhere? If not, I'd be interested in looking at a sample if you can email me one at acroscript at gmail dot com.
It might be related to the issue discussed here: http://kb2.adobe.com/community/publishing/885/cpsid_88564.html
I just ran into the problem as well. To resolve it, I had to open the form in Acrobat then delete and recreate the fields what are not showing text. I know this is a pain but it seems to be the only way to fix the problem. Going forward, I'm either going to have to upgrade the acrobat program to version X or stop using the form wizzard. It seems that fields created with the wizzard act weird in reader x. Either that or wait for what ever the bug is in reader x to be fixed.
This fix works for all fields except digital signature which in reader X does not do anything when clicked.
