compose window size changed

[soalivetoday]

Hello, I recently started using Roundcube with a new web hosting company for my business emails.  Recently the default size of the compose/reply pop up window changed to an awkward size.  I can manually adjust it but I can't figure out how to save it to the initial default size.  I thought it was a Firefox issue at first but it appears to be isolated to this webmail.  Any suggestions?  Thank you.
