For some reason, my Apple Mail will no longer allow me to attach anything to an email either to my apple mail account or to my gmail account. I just get a grey box with the words "BLOCKED PLUG-IN". Something in my computer is preventing, or not allowing me to attach anything to an outbound email. Does anyone have any idea what this is caused by and how to fix it?? As of now, the only way that I can send any attachments is to go to Google mail through a browser online and draft-attach-send my mail from there. Can anyone sort this out for me?
