Check Boxes not selectable in Windchill

Has anyone experienced issues with selecting the check boxes while using Windchill?

We are seeing common yet sporadic reports where the Windchill user cannot place a Check mark in a box for objects list in a WorkSpace or in the Cabinets location. The workaround so far is to Refresh the page then the functionality usually works, but may return at any time. This occurs in the Embedded browser and with a standalone Internet Explorer 11 browser.

Shown is an example.

We are using Windchill 10.2 M030 and Creo 3.0 M050

Thank you for reviewing this question.
