It can be hard to get good facts from users but yes - this is my

I cannot be 100% sure yet about server setup and I can not vouch for  
EVERY browser but in essence this is correct.

So far this has effected 4 out of about 200 installs (this was only  
released on Saturday). But I had been working with a beta-user who was  
the first, who DID try several browsers and I do know is hosted on a  
Linux/Apache server. Indeed his host is also mystified as they have an  
AHAH based example page which works just fine.

This has to come down to an environmental/set-up issue (I assume) so  
this morning I have emailed all four users and asked them to supply  
answers to specific questions around their hosting set up, their  
WordPress set-up, browsers used and tried, software versions etc. My  
aim of course is to try and hunt down the common denominator but like  
many WP users who run blogs, mostly these folk are not technical and  
it can be hard for them to understand the issues and respond  
accordingly.

Whether, when the results are in, something will stand out I do not  
know but meanwhile if there are any tests of ideas anyone has I do  
have at least one effected user who is willing to try just about  
anything!

And I am grateful for you coming back to me. its hopefully going to be  
something basic which are sometimes the hardest to find!

Thanks and regards
Andy
