html - Scroll don't work, if mouse above fixed block -

I have a problem if Fixed block on my mouse page is blocked from this block My example:

body overflow: hidden; Padding: 0; Margin: 0; }. An_block {display: block; Status: Completed; Width: 100%; Height: 100%; Background color: # e0e0e0; Hidden flurry; } Menu {display: block; Width: 100px; Height: 200 pixels; Background-color: #FFDDR; Status: fixed; Top: 0; Correct: 0; Z-index: 3; } .content {display: block; Status: Relative; Top: 0; Left: 0; Background color: # a9eceb; Width: 100%; Height: 100%; Z-index: 2; Overflow: scroll; }

  body {padding: 0; Margin: 0; }. An_block {display: block; Status: Completed; Width: 100%; Background color: # e0e0e0; Hidden flurry; }. Menuu {display: block; Width: 100px; Height: 200 pixels; Background-color: #FFDDR; Status: fixed; Top: 0; Correct: 0; Z-index: 3; } .content {display: block; Status: Relative; Top: 0; Left: 0; Background color: # a9eceb; Width: 100%; Height: 100%; Z-index: 2; }
