In Writer, using middle mouse button for automatic scrolling (Tools->Options->LibreOffice->View) does not work anymore. Simply nothing happens on middle mouse click. Tested with 4.1.0.0.beta1 and newer, up to (and including) 4.2.2.1 under Win7x64. Also tested with 4.2.1.1 under Ubuntu 13.10 x64. Worked OK with 4.0.6.1 and older -> regression (and it's a usability issue, so severity major). In Calc, this function works as expected. In other modules (Impress, Draw) this function has never worked (see bug 66410 that is a separate issue).
for me not reproducible with LO 4.2.1.1 (Win 8.1)
