jstro,
I too suffer from the blank screen syndrome, but know how to avoid it. (I'm using Netscape 7.2).
The problem occurs when you try to scroll down the thread -before- the text formatting tools have loaded above each text editing box on the page; if you just wait long enough for the whole page to load in its completion (ie. don't scroll or click anything) then all should be ok. The problem lies squarely with the new PHP forum programming and appearance. The Renderosity Forum (all of Renderosity's forums, not just the Writers' Forum) is the only site where this problem occurs for me.
I'd personally like to see implemented an option to disable the aforementioned text formatting tools.
