Error with viewing some Facebook pictures

Hi. I am wondering if any1 else is experiencing an error with Facebook pictures.

Sometimes but not every time that I open a picture on Facebook and then close it , a thumbnail of the picture tays on the screen. If I am in any other Facebook page or picture. When I go out of Facebook its not there but when I go back into Facebook it's still there.

I need to switch off my iPad to e his to clear.

Any help would be great

 

I got the same problem; the thumbnail image in Facebook doesn't go away! Help, please!
