Wndows Media Player

Hello,

When I play any type of video or movie file, when the reproduction starts it

appears no image on the screen, only after I maximize the screen to full

mode the image appears, the sound runs normal but only after this prossiger

I am able to visualize the file played.

After this I can resize the screen to smaller or bigger again and it keeps

normal but when I start playing image files it always appears this to me.

Thank you for any suggestion to solve this problem.

Carol
