Problem with Control+PageUp and PageDown

[Michel Peterson]

Hi, I'm having this problem for which I can't find a solution anywhere.

Whenever I am within Screen and I press Control+Page(Up|Down) the  
right escape isn't passed to the running app, in this case vim. But if  
I press, Control+V and then that combination I can see the right  
escape sequence ( [[6;5~ for Control+PageDown ).

Any help is greatly appreciated.

Thanks,
Michel Peterson
