When the mouse cursor is located inside a comment, vertical scrolling (either using the mouse wheel or the main scrollbar) scrolls to the bottom of the page and then from the top again... To reproduce this bug: 1/ Start a new text document 2/ Write some text until the document is 3 pages long 3/ Insert a comment on page 2 4/ Position the mouse cursor in the comment box 5/ Scroll up or down and verify that although it seems to scroll When the comment is so long, that it has its own scroll bar, using the mouse wheel scrolls normally through the comment, as expected. When positioning the cursor in the main text area, the mouse wheel scrolls through the pages as expected. If the mouse cursor is in a comment that is small enough that it does not have its own scrollbar, the expected behavior is that the mouse wheel or main scrollbar should not result in any scrolling occurring at all.
