Tomcat/Windows 2003 page mangling

Hi guys,

We're running Tomcat/Windows 2003 with a number of JSP pages and have found some very odd behaviours. The biggest one is that the page seems to get regenerated in random places, like:

|----------------------------
| This is my page
| some content...
|
| |--------------------
| | This is my page
| | some content...
| |

So, the page is being generated twice in a single page. We've never seen this before - and it only happens sometimes.

Any suggestions?

Any help with this is very much appreciated as we're completely at a loss.

Cheers,

Steve

Just to add a bit more, we're getting the following from the server:

javascript: op%00p%00l%00%1A%00%01enFirefl%00%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A<!DOCTYPE HTML PUBLIC

Which is supposed to read openFirefly - and then it inserts the page again (as indicated by the HTML PUBLIC. The java script isn't anything special.

Cheers,

Steve
