If you would like to customize the placement of the pop-up windows in the WLM application, you can use a manual ISPF function. You must place the cursor anywhere on the active window frame and press Enter. ISPF acknowledges the window move request by displaying WINDOW MOVE pending message. Then place the cursor where you want the upper left corner of the pop-up placed. press Enter a second time, and the pop-up is moved to the new location.
There are some other options for moving pop-up windows. For more information about them, see ISPF Dialog Management Guide and Reference.
