Hi,

i have an executable which works fine. When started it shows a MainWindow and a login (q)dialog (which prompts the user to enter username/password).
Everything works fine.

When i now copy the complete directory which contains the executable an all Qt DLLs + mingw DLL to another host which has not Qt installed, OR when i create an installer package (with nsis or installJammer)
and install it on another host the MainWindow does not appear if the executable is started....
Very strange......

I start the executable and only the login dialog comes up......After logging in (the dialog exec finishes) the MainWindow pops up....
How can there a different behaviour between host where it has been compiled and another machine?

Any ideas?
