Hi! I installed OpenRCT2 yesterday and I got addicted instantly again. But now after restarting I can't close any screen I opened anymore. So for example, I have started a new scenario and automatically the screen of the entrance pops up. I can define the price, open the park, but I can't click the right corner 'x' and close this window. Any other window I open I can not close either. What can I do?
