I'm currently running SH3D 5.3 beta on a Windows 7 laptop. Regardless of whether I use the wireless mouse or not, moving my cursor over the 3d view window causes the view to change as if I'm holding down the left mouse button. I've tried every version of SH3D from 4.8 to 5.3 beta and have the same issue. 5.2 was completely useless because clicking the mouse inside any windows/menus had no effect. My drivers are all up to date and SH3D ran on this machine just fine until I downgraded from Windows 10 back to 7. My mouse works fine in every other program. Any ideas?
