When using qListForm to display a Rich Text field, we are using the Document Manager in the Enhanced Ribbon to add attachments to the List item:
n

n
n
However, when you try to add a document over 500kb, an error is thrown:
n

n
n
If however we try to upload a document through the OOB attachments section, that works fine with the identical document:
n

n

n
n
This issue is happening in both IE and Chrome with QA 6.4 installed. Is this to be expected and if so, how come?
