[CMake] ACE + Qt 4.1 Problem

[Pierre Malarme]

I build classes that use ACE to connect to a device with TELNET  
connexion.
When i test the classes, there is no problem, and it work good.

I make a GUI using Qt. When i test the GUI there is no problem.

But, when i try to use the GUI with the telnet implemenation, my os  
freeze and the software can't connect to the device.

I don't understand why.

thanks for help

Pierre.
