Hello Jon,
The exception from your previous email* shows the problem:
[root at localhost BTOAD]# mono RMScreenShot.exe test.jpg
> BTOStudio RM Client ScreenShot Utility
< ERROR > Fatal Error: System.NotImplementedException: 0bbp
depth not
supported.
So for some reason (is X running? remote access??) the current visual
returns 0bbp which is unusable to create a screenshot.
Are you able to run GUI (e.g. SWF) apps from your terminal session ?
Sebastien
