Some users, but not all, are getting an error message "Please select the Client's locale" when they press a button that has a single line of code on its click event: xfa.host.resetData(). The button has the default locale selected in its properties. The form has had the Reader extensions added, but the same thing is happening on the non-extended form.
The users are using Acrobat Reader 7.0.5. Users with Reader 9 or Acrobat Pro 9 are not having the same issue. I could change the button's locale to English (USA), but that doesn't fix it (I tried) and all the other buttons are set to default locale and work fine.
This is an 11th hour glitch -- we're supposed to distribute the form tomorrow if at all possible and this is the first time I've seen this.
Any help greatly appreciated!
