Zoho CRM Adding Duplicate Items

Zoho CRM Adding Duplicate Items

Hello, I'm having trouble and Zoho Support says it can't be something wrong with Zoho in this case.  When adding a new note or a meeting or anything in Zoho on occasion it adds it twice.  I have tried in IE and Firefox and I KNOW I am not clicking it twice.  Has anyone else had this issue?  It's really annoying.
