 There have been reports of the read-only property (see [#6](https://github.com/geek1011/dictutil/issues/6) and the threads on MobileRead for more details) not having an effect since at least 4.20.14622. This seems to be due to other checks in the code (for IsSynced and the file size) preventing the read-only one from actually being checked under some conditions. Additionally, some people have had problems marking the dictionary as read-only to begin with (this doesn't seem to be an issue on Linux).
