Just as a 'case' I have used netscape on Cygwin Xfree - over a 33.6k MODEM :P yes it was dog slow ... (300ms latency i think...) but it Did work ... ssh X compression helped ALOT - i managed to get my marks from a university server which includes filling out 4-5 forms - a few dialog boxes poping up. etc in only 2 and a half hours. *snicker* if my university let people access their internal database servers by proxy server - life would be sooo much better... :P ----- Original Message ----- From: "Brian Genisio" <[EMAIL PROTECTED]> To: "Alexander Gottwald" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Saturday, January 12, 2002 4:53 AM Subject: Re: [EMAIL PROTECTED]
