Help!: Following roads freezes my browser

Hi there!

I like the site and I discovered it at a pretty early phase. Lately though, when I map a bike ride &  whenever I try to activate the "follow roads" option, I get a "please wait" message in my browser and all I can do is close the application. I waited for a long time, leaving my pc on for the night, but nothing happened. It comes with both IE7 & Firefox. It' pretty frustrating. Is this because I try to map rides in Hungary??

 Thanks,

Chris
