This is a bug happening on Windows 7, R99.
Auto scrolling the window
How to reproduce:
- Start any project with many resources to make the lateral scroll bar happen inside the resource window, for example;
- Select a bottom resource at that windows and drag it far around, without releasing, to make the scroll bar go to the top, then, leave the resource on any place of your canvas.
- Your scroll bar will follow the mouse, without any click or anything else, it's detecting the mouse position and scrolling down/up all the time, looping and consuming CPU resource.
- The only workaround is close C2 and re-open it.
