Cannot attach email

Ok so this problem has been driving me crazy for a while and I simply just have not had the time to check it out until now.

If I click an email in the crm form a contact, the sugar email pops up, and when I try to attach, the button has no response.

Looking at the console shows no error.

If i go incorrectly into the email module, add file button does work and I can proceed.

Does anyone have an Idea as to what the issue could be?

Thanks!

PS this happened once I tried the upgrade to 7.2 with the new responsive theme, the old theme doe snot have the issue.

Upgrade to SuiteCRM 7.2.2 to resolve your issues.
