@ fernas : If something like that happens to many different games in a similar way, it’s quite likely that another program is interfering with vorpX. Many programs also try to hook into games and can create such an conflict, not all of them are obvious. This may be a virus scanner, a graphics driver add-on, a chat program that can display notifications in games etc. If you didn’t do so already, please check the trouble shooting guide in the help for hints in regard to possibly conflicting programs. Please also try to reinstall vorpX to minimize the chance that the issue is caused by a corrupt file.
