Someone sent me a bug report about using xword with the LCARS theme. Apparently, the theme sets the background of buttons to the color black, but the on-screen keyboard letters in xword are also black. This makes the keyboard completely useless. I tried to find a programmatic way of fixing this. Basically I added a hack to set the background of the keyboard to white, but it's not an ideal solution and is frowned upon by GTK programming standards.

Fortunately, I found a supported way around the problem. GTK allows you to set a theme on a per application basis. If you have Personal Menu installed, you can set a command to launch xword with a default theme (with white buttons). In Personal Menu, create a new command entitled "Xword" and enter the following in the "Command to execute" field:
When you launch xword with this 'shortcut', buttons will be displayed with the default theme 'echo'. (You could also replace 'echo' above with one of the other built-in themes, like 'felicia' or 'glasser'.)
