I wish there were more utilities like this one. No, not ones that remove corrupt font cache files, but ones that are small, fast and effective, and do just what they set out to do, no more and no less.
Whenever I have had problems with the stability of InDesign or Word (well, problems that aren't related to Application Enhancer, but that's a whole other story), this app has done its work and had me back on the job very quickly indeed. No need to even restart the computer.
Five stars all round, and thank you If Then!
