Apologies - we're working in this area, and some layout might be a little ugly.
Reversing the arrow colours fails?
Two solutions:
1) Check your settings under "privacy" in your browser, looking for references to Cookies.
2) If you've bookmarked the page, add "?rev=1" to the end of the bookmark.
i.e. www.seabreeze.com.au/graphs/wa.asp
becomes
www.seabreeze.com.au/graphs/wa.asp?rev=1
