I notice that at some point the Preferences screen has started showing this message: "Note: After saving, you have to clear your browser cache to see the changes: Mozilla: click reload(or ctrl-r), IE / Opera: ctrl-f5, Safari: cmd-r, Konqueror ctrl-r."
Is there a reason for this? Nothing in preferences should require forced reloading; saving the preferences updates the user_touched timestamp and forces subsequent page loads to refresh if the client's cached version was older than that point.
I seem to remember this message was created for the user stylesheet/javascript bits.
