Microsoft Project Window Minimizes after Launching OnePager

Certain versions of Microsoft Project have been known to minimize when the OnePager window pops on top. This is harmless, but if you prefer that Microsoft Project window stay up, there is a simple registry setting you can change:

  1. Launch your registry editor, often known as regedit. If you don't have permission to do so, ask your helpdesk.
  2. Navigate to Computer\HKEY_CURRENT_USER\SOFTWARE\Chronicle Graphics\OnePager. See if you have a setting called SuppressMinWin. If you do, ensure it is set to 1 to tell Microsoft Project not to minimize:

  3. If you don't have the SuppressMinWin setting, you'll need to add it. Right-click anywhere in whitespace, and then choose New > DWORD (32-bit) Value:

  4. Add the DWORD called SuppressMinWin and set its value to 1:

  5. Close the registry editor. Then, close OnePager and close MS Project. IMPORTANT: You must restart MS Project and OnePager in order for these changes to take effect. You do not need to restart your whole computer.
