As you guys must've noticed by now, I'm active (not to my fullest like back in 2014 though) enough to edit and post the findings I got back a year ago, here's one of them.
I was flying through San Fierro as usual, Hydra was the vehicle in use. Everything tip-top, nothing gone wrong until I had to do something so I paused my game and there, the menu glitched to a higher contrast and wouldn't let me resume nor get me back to Windows 7.
The first time this ever happened to me was back in the mid-2014 when I was a newbie in SA:MP, by that time I thought it was just another SA:MP thing. But the picture that you are seeing right now happened in 2015, and that too in Single Player, means it is a game problem rather than a mod.
Anyone else faced this? Should this be added as a glitch?
