VNC Connection Problems

This post is for any other VNC users.

I use the free version:
http://www.uvnc.com

Now, what I have noticed on many occasions this error:
Framebuffer update rectangle too large.

This is my scenario...

On a cold, rainy night, which I prefer over sunny days, I connect from my laptop into a PC many states away, to test VNC into my base PC. All is good over the HTTP connection. I test 2 or 3 times. All good. Now, and this happens each time, I travel and then repeat the same methods. However, that is when I get the above errors. No idea why. I go home to check my main PC and everything is running fine.

Would anyone out there have an idea why this happens?

EDITED to fix correct program link.
