(V1.3, 1.4) Repaint on maximize problem

os:windows7 professional 32bit
cintanotes version,both 1.3,1.4.but 1.2 is good.
when maximize a note window,the content window do not maximize with the frame.
this bug occurs under windows theme "windows 7" or "windows classic",if change the windows theme to "windows basic",the problem will solved.
