When I am clicking to contact now, no windows appear.
Is TabSRMM window appears on taskbar?
If yes:
In Windows 10, 8, 7, and Vista, hold down the “Shift” key while right-clicking the program in the taskbar, then select “Move“. In Windows XP, right-click the item in the task-bar and select “Move“. Cursor will be placed on window caption so you can hold left mouse button and move window to the visible part of screen.
