I have updated the test page at 
<http://tinyurl.com/2qll7h>http://tinyurl.com/2qll7h with test 
results from Joshue O'Connor, Sailesh Panchang, Charles 
McCathieNevile and Steve Faulkner. I will probably get some feedback 
from Linux users later this week. Hopefully, I will also get results 
from people using HAL, IBM Home Page Reader and other AT.

Best regards,

Christophe
