I just recently bought a brand new laptop with Windows 10 on it and installed LOTRO. When I open the game, it will load as far as the character selection screen, with music and animations playing fine, but I literally cannot click anywhere. When I open up OBS, however, I am able to click the different buttons on the character selection screen, but the window minimizes constantly, so that I barely have time to click on anything before it minimizes again. I have searched all over the internet and so far have not found anything that seems to match or fix my problem. Does anyone have an idea of what I can do to get the game working properly?
This sounds like another application trying to take control rather than a Lotro problem. Try shutting down non-essential tasks in task manager and trying again.
