i've got some strange problem here;
when i'm working via the internet (from WinXP on ISDN => various Win (XP)
this connection is already slow (with some systems, they 'freeze' for a min
however, when i try to work on a PC (Win98) on my LAN (100mbit full duplex)
i cannot do ANYthing without having to wait
AT LEAST 15 seconds until the mouse responds !!
does anyone have a solution, or a tip to get this working as fast as, for
example (hey, don't shoot me) PCAnywhere or Windows Remote desktop?
i don't care about more than 16 colors (256 would be nice), but it should be

I do recall reading in the archives that work was
being done with RealVNC folks to deal with it. I
don't recall if the exact CAD tool was mentioned.
I don't suppose that the change in code could be
easily incorporated into TightVNC? Tight encoding
really helps sometimes, and I'm not sure why
there hasn't been a merging of efforts.
