Re: [Htmlvalidator-help] html tidy 0.7.9 crashes FF 1.5.0.4

[Marc G. <mg...@sk...>]

Hi Andy,

the last validation page you gave is the faq of my site. It is probably=20
not the
page crashing the browser.

Please give also give me the following info:
- which OS do you use (Linux32 bits 64bits Windows ??)
- which processor (AMD 64 ??)
- Please give me a step by step that would allow me to reproduce the issu=
e.
- Do you use accessibility checking, which level ?
- Does it happens always, or only with a specific page
   - If so be sure to send me the specific page. It is probably a bug in=20
Tidy.

Thanks by advance,

Marc
