When the code that sets the window property and executes vid() is run, the file browser is covered by the console screen.
In this state, you cannot return to the file browser unless you type exit into the console.

window{
 width=128
 ,height=128
}
vid(3)

I don't understand the underlying mechanism, so it's hard to offer suggestions for a solution...
but something like these may be what we need.

• Restrict the use of window and vid() at the same time.
• If a new console is running, even in a window application, close window and console after execution is finished.
• Running window application from CART RAM is always done on the console screen.

I hope i can find a simple solution.
