Hi,

on my Vista notebook (Vista Home Premium, SP2) there are two things...

-run Uniprint.exe AFTER VirtualRPC,

-minimise VirtualRPC to the task bar and leave it there for something like ten minutes,


...which invariably lead to the above error message.

Afterwards the window containing VRPC is empty - i.e. it shows whatever was behind it at the moment I tried to go back to VRPC after doing one of the two things above.

I've so far not found any way to get VRPC working again short of quitting from Windows and re-running VRPC.

Is this an effect singular to my machine, or is this a more widespread problem with Vista?


Kind Regards,

Jochen

Ooops,

my eye sight must be failing; I only just noticed that there is a very similar thread further down the page; maybe Aaron should move my first message there?

There are several posibilities. Firstly make sure that UAC is disabled.

The error indicates that for some reason VirtualRPC couldn't grab the screen buffer it needs to display the RISC OS output. This could be caused by:

A problem with the graphics drivers on this machine
A fault with DirectX
Something else messing up the DirectX workspace pointers.

It's not (as far as I am aware) a general problem.
