Sometimes DM or Evolve will open but not show on Screen,
this most the time happens when users have multiple monitors, and the Software is opened Off screen.
Best to use Shift +Right click on the Icon then click move , then hit the right left Arrow X2 next use the mouse to move to screen.
Below is something I took out of the web, but above helps every time.
Get Hidden Windows Back with a Keyboard Trick
There’s also a simple keyboard trick you can use if you don’t want to rearrange all your windows. First make sure you’ve got the off-screen window selected as the active window. You can do this by pressing Alt+Tab until that window is active or clicking the associated taskbar button.
After you’ve got the window active, Shift+right-click the taskbar button (because just right-clicking will open the app’s jumplist instead) and choose the “Move” command from the context menu.
At this point, note that your cursor changes to a “Move” cursor. Now, you can use your arrow keys to move the window. You should also just be able to tap any of the arrow keys and then move your mouse slightly to have the window pop back onto the screen.
This trick will work on any version of Windows, but note that on versions before Windows 7 you just need to right-click the taskbar button instead of Shift+right-click to get the context menu. It’s a handy little trick for solving an somewhat rare—but definitely frustrating—problem.
