WPS Office on Elementary OS: How to fix ugly Open/Save windows

The most popular alternative for Microsoft Office is Libre Office. But there are lot of compatibility issues between MS office and Libre Office. WPS (Kingsoft) office is a free (There is a paid version as well) alternative for MS office users with highest compatibility. You can install the free or paid version of WPS office in Elementary OS. GUI of WS office is much better than Fibre office  and everything works fine.

The only problem I have observed is ugly Open/Save windows. See the screen shot below.

The fix for this is installing following two packages on Elementary OS.

sudo apt-get install gtk2-engines:i386

For freya beta

sudo apt-get install gtk2-engines-murrine:i386

For Luna

sudo apt-get install elementary-desktop

The look after fix is below.
