[Lazarus] IDE multi-carets issue

[AlexeyT]

I have 4 carets on lines

         c.SetValue('/dialog/fl_btm/posx', FFormFloatBottom.Left);
         c.SetValue('/dialog/fl_btm/posy',  FFormFloatBottom.Top);
         c.SetValue('/dialog/fl_btm/sizex', FFormFloatBottom.Width);
         c.SetValue('/dialog/fl_btm/sizey', FFormFloatBottom.Height);

at start of str. Now i press Right key to move carets to right==> they 
disappear.
