Re: [Summary-Talk] Corrupt DNS cache file?

[Luc Dubois <luc@xxxxxxxxxx>]

Hi Jason,

Since I'm feeling adventurous I'll go for the second option. Is there
anything I should pay particular attention to when saving the
dnscache file, such as line endings, encoding, etc... I will edit the
file on Mac OS X with BBedit (a snap to remove all the lines
containing asterisks) but Summary is running on my Windows XP
machine, that's why I ask.

Thanks for the support,

Luc
