While analizing the code for the mouse movement I've discovered that we did a lot of uneeded things: Set the color, the pen, the size of a fixed-colored line, twice. We also deleted-newed the same Pixmap / Text for every mouse movement so now we reuse the 'entryToolTip' that consists of a huge line and a pixmap, and after that we add the other tooltips that are not static Also, reduced a lot the number of calls to expand() (that did a lot of math).
