Throwing objects to Virtual Machine in Unix [message #37635]

Hi.

Maybe you can give some help here.

I'm starting to work with objects. And already have a problem. and I don't
where is my mistake.

This is a simple program where I do a matrix with a circle on the centre.
And I want to view it as an object using IDLgrImage, so I build the
hierarchy for that and the widgets needed. The event is only for managing
the resize of the window.

Here is the problem: If I run it in Unix with IDLde opened everything is
okay. It is okay also if I try to run on VM in windows. But if I try to run
it on Unix with VM is gives me an error:

% Restored file: IDLVMMAIN.

% X windows protocol error: BadMatch (invalid parameter attributes).

Xlib: sequence lost (0x10221 > 0x22e) in reply type 0x13!

Someone has the idea of what's wrong? It is something specifically for VM on
Unix? How can I fix it?

The complete code of the program I'm trying to run is on the end.

Cheers,

Nuno.
