              The ghost script fonts can help as they are read well by Java's awt font class. The problem is more an issue of the font metrics reported from the AWT font library in Java. The Pro version has it's own proprietary font engine that doesn't have the same limitation.

              It would be appreciate if you can post a sample file so that we can take a closer look.

              I am experiencing the same issue, using the lines of code taken from the "ViewerComponentExample".
              I am using the OS 4.2.0 download, running on Windows 7 64 bit, java 1.6.0_23.

              I am unsure I understood this correctly : can it not work properly without installing ghostscript fonts?
              Thanks in advance.

              The PRO version can read embedded font information and get the correct height of glyphs. The OS version relies on font substitution and as such can't always derive the correct height. A fix went in for this release, PDF-251 which help insure we correctly read the AFM cmap files. This extra font information seem to help with getting the correct glyph width. Users should also make sure they install the ghostscript fonts as they closely match the font metrics defined in AFM cmap files.

              This is only effects the OS version.

              I am attaching the screen shot of the applet viewer which shows how the search results/highlighting looks like.
              Its a little off from the word, mostly its down the search term.
