I am running Gloria. For some reasons I had to uninstall OpenOffice.org. After that I reinstall OpenOffice.org from repository. But when I reinstall it won't follow the theme style (shiki-mint comes with Linux Mint 7 by default) that I am using. I mean OOo don't have the the style of my theme. Especially selecting items & input boxes. Here I attached two screenshots. Before I uninstall OOo it looked like the picture # 02 (talking about drop-down menu, theme etc.) which is given below. But now it looks like something Windows Classic style. Note that rest of all applications are working well with the theme style.
