If I receive an e-mail with a link to a web page(blue).WhenI click on it I can't
make a connection.
Problem == not working link in e-mail message!
Are you sure that K-meleon is your _default_ browser?
Mail configuration in K-Meleon is for running mail-reader.
Single slashes are OK.
for example I have in "mail configuration":
"D:\Program Files\BatchRun\BatchRun.exe" -execute "D:\Program Files\BatchRun\NoSpamOEXP.brs"
(batch run sequencially: spamihilator, oe-qoutefix, OE)
and all run OK.
