>>The original message was supposed to go in Chatter, News. However, after I selected 'Chatter' in the forum section, the category combobox still reflected the categories for the VFP forum. I reselected the Forum numerous times to no avail. The category combobox is not refreshing as it should. I finally decided to change the message to the Universal Thread forum and enter the problem instead. The category combobox still shows the VFP categories, so I chose chatter. When I tried to 'send,' I received a page not found error. I clicked on back and then tried to send again and this time I received the message 'the category does not match the forum' error message. The page refreshed and I was finally able to choose the Universal thread category in the universal thread forum.

>>I am also experiencing slow response times when I try to view a message. It is possible that a communications error occurred while I was trying to create the message so the combobox could not refresh correctly. Is anyone experiencing this today?

>When you change the forum dropdown list control, it sends a message to the server to refresh the category. In the last two weeks, has this ever worked for you? This is the part that didn't seem to work on that situation.

Yes, in fact it worked a couple of times today and worked just now when I tested it. It seems to fail intermittently...
