[Mageia-discuss] Applications open and close

[Paul Simon]

Mageia 1.

Most times when I open an application from the desktop or command line it 
will open and in about one second will close, i.e., Firefox. Recently 
installed Opera behaves normally.  I've lost Webmin after upgrade. 
Sometimes the app will open and will close with a mouse click.  This all 
seemed to happen after I inadvertently change the application open style and 
back.

I would like to fix this without reloading the OS.

Thanks for your help.
