Some revisions require an updated JAR (for example updating your 2.2.30 jar to 2.2.31) and others require a browser cache clear to capture an adjustment to the Periscope build.
The version of Periscope that you have installed is displayed at the bottom middle of the dashboard - for example it will say "2013 -Activelogix (2.2.31).
This varies according to the browser your using (Chrome, Firefox, IE, etc.) and you can find detailed instructions for each browser at
It's not a bad idea to clear your cache on occasion to capture any recent adjustments that we've made to Periscope.
JAR files can also be created to store files, much in the same way ZIP files are used.
Files with the extension can contain multiple files that have been compressed into a single folder or one large file that has been compressed to achieve a more manageable file size.
If there is a "-M" next to the build, it denotes that it's a "military" or "offline" file version.
We notify you that your Periscope JAR is out of date with an exclamation point icon at the bottom of the dashboard.
The task seems to run OK, but the JAR doesn't get updated.
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer.
It can open over 200 different types of files - and very likely yours too!
Clicking on the icon will tell you the latest build available as well as what is included in the update. Clicking "apply" will generate an email to tech support at Activelogix as a request for an updated file so we can respond with the appropriate file.
Other minor fixes and adjustments can be captured with a cache clear of your browser history.
