"Beautify" Problems with split Link Addresses

I am not sure this is where I am supposed to ask questions, but here it is:

When I try to 'beautify' my HTML, Tidy splits some of the URLs onto two
lines. They are then interpreted as having blank spaces within the address,
rendering them useless. How do I stop Tidy from breaking URLs when
'beautifying' the text?  Thanks.
