TM1 Forum

A user has cube open and clicks on a dimension to select a subset. The subset window opens but then appears to disappear and the user cannot find it. TM1 is locked-up (user cannot do anything else) until the subset window is either closed or a member selection is made but they cannot see the subset window. How do we resolve this?

Could be that the window is off the viewable area of the screen.
Try using the Windows key + the arrow keys to bring it back into view - you may need to repeat directions to get it back.
This often happens after you have had another monitor connected.

I often use alt+space keys to show the little "move" menu, and then use arrow keys to bring it back to the center of the screen.

The previous answers cover how to get around it. If you want all the ins and outs of why it happens, you'll find them here:
