Can I use LO 3.5.1 on netbook with 1024x600 screen resolution? If not, what do you suggest?
Yes, you can. In fact given the default small icons used in the interface it provides more “workable” screen area than some alternatives.
Since the netbook has a (small 
) widescreen resolution I prefer to move the main toolbars to each side of the usable area so that I can see more lines/rows.
Even using larger font size for Windows (Asus Font Sizer: Large) I haven’t found a dialog that didn’t fit the screen (although at that font size you need to scroll some of the Menus)
