Multiple Bugs in both Firefox and IE for zoho mail

Can we get a fix for zoho mail on the following.

Spell check - 2 common issues here. once email is checked we cannot left click for spelling options. For the most part will only let us check once.

Email font colour - can only change font colour once. Button sticks and stays yellow. Without refreshing the page cannot change twice.

Email font size- Nearly every email we are producing to our clients changes font size and type.

Ive reported a problem and sent a request but still nothing fixed. Please can we get this sorted before I just move awy from Zoho and back to windows mail.
