So recently I got a new Red Dragon k503 Keyboard and up until this point it has worked perfectly. However a couple of hours ago I noticed while playing a game that if I held down the S key, the A key, and the 4 on the top of my keyboard all at the same time then the S and A register but the 4 doesn't. This is weird because if I hold down anything other than S and A (for example W and Q) and then I press the 4 key it works completely normal. I also tried holding the S and A key and then pressing another number but all numbers work fine, it only happen with the 4. I understand this is a strange problem and it wouldn't really be an issue if the keys were something like J and H but unfortunately it gets in the way with a lot of the games that I play. I've researched if maybe this is a common problem but sadly nothing pops up, which leads me to believe that this issue does not happen often. If anyone could give me some advice on how to fix it that would be great! Also if anyone has anymore questions feel free to reply and I'll try my best to answer them as well as possible.
