I used Sogou Pinyin IME for many years. It is easy to use.
Save your time, the conclusion is: Do not use Sogou Pinyin IME.

Here is the problem I found last month.
The blue circle with the mouse arrow is always there. When I boot the PC, it is normal. After a while, I opened a browser or ran some programs, and the circle came.
I tried to check every spot in my Windows installation. Such as system drivers, antivirus programs, open Firefox, or Chrome. But the same results.
I knew something is running behind the screen. It is the reason for the blue circle.
I did not think about Sougo pinyin. I used it for many years, since Google Pinyin is gone.
Until I saw some news on Google News.
Vulnerability in Tencent’s Sogou Chinese Keyboard Can Leak Text Input in Real-Time
Almost Every Chinese Keyboard App Has a Security Flaw That Reveals What Users Type
So, I uninstalled the Sogou Pinyin IME. I re-enabled the Microsoft Pinyin.
The blue circle disappeared immediately. Now, it has been almost one month. I believe that the Sogou Pinyin did something behind me. I don’t like it. I know nobody likes this kind of thing. I have to post it and let everyone know it.
