The browser Chrome includes a plug-in for viewing PDF files, this is designed to give you faster browsing to this type of file.
Unfortunately, the Chrome plug-in is basic and lacks many useful features like pagination and bookmarks. It also prevents the CAA PDF form being 'submitted' on-line.
To overcome this problem in Chrome, it is possible to turn the plug-in off and use the standard Acrobat reader software to complete and submit the CAA on-line forms.
To do this, you need to have your Chrome browser open and type chrome://plugins/ into your address bar, when this has opened up options you will be able to turn off the Chrome PDF plug-in.
When you have done this you will be able to submit the PDF form.
