netbeans creates problem on system hybernation ?

1. When the system goes into hybernation for a long time say - around 7-10 hours, netbeans in my system begins to pixellate. When I scroll using mouse, multiple instances of the mouse pointer is seen on the screen and it persists (image shown). This was existing for a long time.


Another problem i noticed today made me write this post.

2. Even new files are not opening after hybernation.

Even netbeans restart is not a solution. I need to restart windows.

Is there others who are having the same problem? Or am I the only one?
