dear
i was the rondcubemail in a mail server. that's great. but i have get a problem in the "setting" button. the plugins button display correct. not in a line. please see the attach file to detail.
I have checked IE6 and don't have this display issue using RC 0.4.2.
What version of RC are you using?
Are you using the default skin?
If you possibly can you should really think about upgrading from IE6 to IE8 or another browser as IE6 has many insecurities and an upgrade will give you a much better browsing experience.
