Hi. If you experience the bbPress caching issue (which sees to manifest as needing to refresh the page in order to see something you've just posted or as bbPress sometimes showing you as being logged in under the wrong username) please post you browser details to this thread along with the symptoms.
I already have details from Oopman and Synkronos:
Opera 9.01
Firefox 1.5.0.6
Also if you have any thoughts about what the underlying cause might be, please post. I might be helpful if people whose browsers don't show the issue post too.
Galeon 2.0.1 compiled against Firefox 1.5.0 (seems fine)
Galeon 2.0.1 compiled against Mozilla 1.7.12 (seems fine)
I'm not 100% certain this is a browser issue. It may be an ISP or configuration issue, or even something weirder.
