QTcpSocket::connectToHost() is blocking the GUI!

Hi jackmack.

I tried to reproduced the error that you get when using fortune client, and it worked ok in my system. No blocking, and no endless loop. Even when I used another non existing IP, the window can be moved around, until the apperance of the error in connection message.

I'm using Qt 4.7.0, and win32-g++ with minGW. Maybe the problem is when using VS2008.

Hope this helps.

Hi,

wow, that's strange.
I will try it also again with the Qt intergrated IDE. I think this is the fastest way to test it.

Thanks a lot.

Hi Arnaiz,

I have installed also the Qt 4.7.0 with minGW and the result is strange!

Running the fortuneclient on clean VM system (64 bit) -> non blocking!
Running the fortuneclient on clean VM host system (64 bit) -> non blocking!
Running the fortuneclient on a clean windows XP system (PC 32bit) -> non blocking!
Running the fortuneclient on my develop system (laptop 32bit) -> it's blocking!
Running the fortuneclient on my old develop system (laptop 32bit) -> it's blocking!

On my old development system I have uninstalled the Microsoft VisualC++ IDE and the Web'n Walk drivers for UMTS access.
NOW IT WORKS! NO BLOCKING OCCURS! That's strange.
