Aside from a complete application makeover which may be needed to adapt it to current usability trends, the application graphics don't look good when the application is maximized (if the resolution doesn't match that of dimensions of the program).
For example in my laptop (1680x1050) if the application is maximized the graphics on top and bottom look flattened.
PS. There may be need for adjustments for HiDPI screens as well which are currently in the rise.
