Hi Till & Falko, It's known that IE7 & IE8 are not the best browsers as it comes to CSS. So, rounded corners defined in css does not work without a fix. But, when using a fix, it is possible to see rounded corners if you using IE7 or IE8, as you can see here: http://188.8.131.52/fileadmin/ind.html However, when we use the same html-file on our own Debian ISPConfig3 server, we can not see the rounded corners in IE7 and IE8: http://wonnebald.typo3surfer.eu/fileadmin/beheer/home/csv/ind.html So, I had a look at the content of the file /etc/mime.types. There we have have a line, like: text/x-component htc Do you know why the rounded corners on our Debian ISPConfig3 server are not shown when IE7 or IE8 is used? I wonder what else needs to be configured, to make it possible.
