The think-cell Elements menu is inactive ("greyed out"). I cannot insert any think-cell elements.
Slides cannot be edited if no presentation is open as well as in an open presentation's Slide Sorter or Notes Page views, and therefore think-cell's menu is inactive.
Switch to Normal or Outline views, either using the button in PowerPoint's status bar or by double-clicking the slide you want to edit in the Slide Sorter view. think-cell's menu should now become enabled.
Note: A slide thumbnail must be selected if the Thumbnails pane is open in Normal view.
Defective third-party add-ins can prevent the activation of think-cell's Elements menu because Microsoft Office does not isolate individual add-ins from each other.
The problem may be caused by Acer's abDocs add-in, which comes preinstalled on some Acer computer models as part of the Acer BYOC Apps (abApps) suite. When abDocs is installed and activated, think-cell no longer receives PowerPoint's application events.
If you want to use think-cell together with abDocs, please contact your computer's vendor and open a service ticket with them. Our experience shows that vendors often do not act if we contact them directly, as we are not their customers. Please pass on our contact data to the other vendor and tell them that we are happy to provide a more detailed explanation of the issue as well as a test version of think-cell.
If the problem cannot be resolved by the above suggestions, please contact our support team.
