'Send Mail' Not Working from 'Activities' tab after switching to IMAP

Hi,

After switching to IMAP I cannot sent an email from my Activities tab.

An error pops up that says: 

"TypeError: Cannot read property 'value' of undefined Zoho crm"

It appears to work from the lead and contact section in that the email pops up with no error but I have yet to discover if it actually sends.

Thanks in advance,
Paul
