I've been trying different versions of LyX. In the 1.5.x mouse wheel scrolled only 3 lines (want screen at a time) and in the opposite direction that is set on my system (Vista64)
Now I've installed the alternative installer 1.6 beta 3. Mouse wheel does not scroll at all; instead, rolling the wheel either up or down return the document to the top (same as Ctrl+Home); further wheel actions have no effect. Is there any setting anywhere that I could change in order to have it right? Thanks
