Hello,
Thanks for your inquiry.
Does this issue occur when opening all documents, or just specific documents? I tested your scenario but found the form can be closed normally. Here I uploaded
my test project, you can test it to open your own document. If the issue still occurs, please provide your PDF file and your environment information, such as OS information (E.g. Windows 7, 64 bit) and region setting (E.g. China, Chinese).
Or if your project is different from mine, please share your project with us for further investigation. You could send it to us (
support@e-iceblue.com) via email.
Sincerely,
Rachel
