Internet Explorer 11: Buttons are hidden or covered
In Internet Explorer 11, the Edit menu or Submit button may be hidden behind the PDF preview area when attempting to create or edit a PDF.
This is a known issue affecting IE11. Please try another browser such as Chrome, Firefox, Edge, or Safari.
Alternatively: Upgrade to Cascade CMS 8.13.1 or later where IE11 users will be prompted to preview PDFs in a new tab.
Google Chrome: Buttons, links, or fields not clickable and drag and drop opens the PDF
In some older versions of Chrome, you may find you're unable to click on any buttons, links, or fields that appear directly above the PDF preview area.
In addition, you may find that dropping a PDF file into the upload area opens the PDF instead of uploading it.
These are the result of a known issue with older versions of Chrome (69.0.3497.100). Please update Chrome to the most recent release.
