Workaround for Quartus II 15.0 Device list cannot be pulled down under the WIN10 environment

I don't know if you're using Quartus II 15.0 in a Windows 10 64-bit system environment. No, the process of creating a new project is to select a list of devices that cannot be pulled down and see only one device model, as shown in 1.

Figure 1

at first I made the mistake of thinking that the Cyclone IV E series of the Quartus II 15 software contains only one device. Later, after trying to find the left mouse button to drag the top left or top edge of the window shown in Figure 1, you can adjust the size of the form, you can see other devices, and then the right scroll bar can also be dragged, Adjusted window 2 is shown.
