When I run my Win32 application the Windows language bar (which is visible in all other applications) disappears after about 5 seconds. It reappears if I quit my application or alt-tab to a different application. If I alt-tab back into my application, it disappears again after five seconds. The switch key doesn't work either.

It seems as if the system somehow has concluded that my application doesn't "support" the language bar.

Is there something I need to do to for the language bar to be enabled? Or something I shouldn't be doing that can cause it to disappear?

The application has a single custom window (where I draw DirectX graphics). I've looked through the arguments to CreateWindow and RegisterClass as well as the window messages that I handle (instead of passing to DefWindowProc) but nothing seems to be directly related to the language bar.

I've only tested this on Windows 7.
