This is also a big problem with DCs and connecting to IPs that aren't
reflectors at all.

My guess is it's the same kind of problem..using blocking calls to
connect(), etc. which will hang till a response comes back instead of the
asynchronous nonblocking calls. But that's just a guess. It also seems
to block when you type in a alphanumerical IP that doesn't exist (DNS

It also solves about 90% of the people's complaints about the connect time
being slow.

Holding down the ENTER key works..but a more elegant solution is CUnnect98
( With QuickConnect turned on, this
program flies. It can attempt connects about 2-3 times a second and you
don't have to wear out your fingers holding down the ENTER key. :)

Aren't deadlines wonderful? :)

I'm positive that he'd be happy to fix it...just up to Martyne I suppose.
Looks like Martyne is still absent though.
