I'm testing Gitso in a Mac OS Leopard for giving support.

When the remote screen is too large, it is necessary to scroll down and up the vncviewer window to see it entirely. However, this is not intuitive in the vncviewer application that comes with Mac OS, particulary when trying to scroll up. Besides, a long cached area appears below the main remote screen.

For those reasons and others, I recommend trying and placing the current xvncviewer in place for the xvnc4viewer.

We have tried this, but it broke in some situations. Though if we can resolve those issues, we may move to it.
