CET 16.0 Patch 2

Summary

Users have reported an issue with the keyboard shortcut "CTRL" not working when attempting to select multiple objects at once. Some of them have also shared that the "Rectangle Select" tool is not working as well. 

Steps to Reproduce

1. Open a drawing in CET
2. Press and hold the keyboard shortcut "CTRL" and drag left across multiple objects
3. Observe issue

Also can occur with the following steps:

3. Attempt to select multiple objects with the rectangle box
