Screen Sharing/Firewall Catastrophe: HELP!

[Hendrik van Eeden]

George,

Other than the firewall issue, I have not other problems with XTension.  Everything is back to normal now, although I don't know what exactly it did to accomplish that.  I messed around and tried different things and restarts and then it worked.  By the way Timbuktu, Chicken and the connected monitor worked all the while.  I do recall that the last thing that I messed with was the Remote Management feature.  I had clicked on it to enable it and of course that disabled screen sharing.  Then I could not longer uncheck the Remote Management option, which baffled me. But then, I don't know why, I was able to uncheck it and everything was fine after that.
So I don't really know what was wrong to begin with nor what fixed it.  Unsettling, but what can I do.

Henk

My problem is not that I don't have screen sharing… my problem is that without touching anything in XTension on my Mini, and ONLY by turning on and then off the Mini's firewall, I have lost control of from 5-10 units I have discovered so far.

I have no manual control over them either from within XTension.
