Explain How to do so!!!

Greeting to you all,

Firstly I'd like to thank you very much for the support which aided me in running the game on my epsx emulator.

And now I want to inquire about a problem in that emulator which is:

When i choose run the game and the prog start to do so and to show the game on full screen mode, a residual of my desktop still appearing in the screen
ie: the game is already now in full screen mode and it is working properly, but there are some areas in the screen wide still showing my desktop and task bar in a fainting view.

This happens not only with this game it occurs with almost all games I do run on it.
So what is the analysis of my problem & what is the solution?

Sincerely
Ivanoviskie
