Well, it has been a couple weeks :-)

Have tried both TightVNC and RealVNC. Haven't tried UltraVNC yet.
Should the client make a difference?

Not encrypted, just password protected. Both boxes are behind hardware
firewalls, and have "holes" for 5900-5905.

Am not using max resolution on the X Display on the Breezy machine,
but am telling the VNC client to size to the remote desktop.

Yup, and that the that it spawned was using over 40 of the rest
of the CPU. Which makes the thing darn sluggish.

Again, if this tool is known to be a problem, and I should just use
VNC, let me know. I had just "thought" that using a kde tool with kde
would give me better performance and would be more reliable.

Thanks again,
