Do I need to install a particular font?
Yes, try any of the fonts I gave links to in this thread:

Then you should select that font in zbedic settings.
It doesnt happen with any other program.
Try to copy the text that contains the "boxes" into a text editor and see if the boxes disappear, which I doubt. The pronunciation part of the dictionary you selected likely uses IPA (international phonetic alphabet), which has lots of glyphs that are not found in standard Zaurus fonts that you have installed.
Again, this is an absence-of-font problem.
