There are times user face issues trying to navigate in the dimension (subset editor) with thousands of elements, and accidentally click on the consolidated element. TM1 Architect hangs and the user is unable to click anywhere, until TM1 displays all the elements under the consolidated element in the property window.
How to avoid Architect Hanging
To avoid this issue of Architect Hanging while all the elements are displayed in the property window, make sure that the Display Properties Window in the subset editor is turned-off.
Once the Display Properties Window button is turned-off, clicking on any consolidated element will be quick and the screen will not go into a hang mode.
