[SOLVED] Cannot open some attached pdfs using Gmail imap

[pcdoctor01]

Cannot open some attached pdfs using Gmail imap (they can be opened using Gmail webmail)
I'm using Thunderbird 68.1.0 64 bit (linux)
When using Thunderbird and clicking on the attached pdf, nothing happens. (the pdf does not open)
This does not happen with all pdf attachments though.
When right clicking on the pdf in Thunderbird that won't open in the gmail imap folder, the save as option is grayed out.
I can copy the problem imap email to a local folder and TB is able to open all the attached pdfs.

Known problem being looked into. Try setting mail.server.default.mime_parts_on_demand to false using the config editor at tools -> options -> advanced -> general (and restarting) as a temporary workaround.

Just for giggles before you sent me the fix, I installed TB 60.9.0 and it was able to open pdfs using gmail imap. So, I figured it had to be a version issue. Thanks again for the help!
