HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Hello, can anyone help? When I click on any clickable element in the HD mod's online lobby, which redirects me to browser pages, my Windows system starts acting up. All buttons get assigned random actions; for example, pressing "U" brings up a window with keyboard settings for visually impaired users, and pressing "TAB" activates a plugin for cycling through open applications (like in Windows 10), and so on. The only way to fix this is by restarting my computer. Has anyone else encountered this issue, and does anyone know how to resolve it? ;D
