Welcome to the Support Community!
Since this issue started after an update, it may be caused by an issue with the installation. To resolve this, can you please try to first back up all your data and then perform a clean reload of your BlackBerry® Device Software? For further steps, please see the following KB articles.
For Windows®: "How to perform a clean reload of the BlackBerry Device Software for Windows" http://bbry.lv/GI9beY
For Mac: "Perform a clean reload of BlackBerry smartphone application software using BlackBerry Desktop Software on a Mac computer" http://bbry.lv/J0UN1U
Please test to make sure the issue with your Trackpad has been fixed before you restore any data from your backup file.
Let me know if this resolves the issue for you.
