Thanks Don I routinely cear caches so I tried switching offContent-Type: text/plain; charset=ISO-8859-1; format=flowed You probably have css compression turned on. There's a limit to how many css and js files IE can load, so to get around that Drupal put them all into one big file to download. It also downloads faster that way. If you need to flush css, go to site configuration -> performance, and look at the bottom of the page where there's a button to clear cache. -don- On 2/9/2012 10:37 PM, Roger wrote:I'm debuging and trying to modify the calendar css because the little blue info field is too small to display sufficient info.
