Forum:Slide & Charge problem

Why when I play Megaman-games on an emulator I cannot charge and slide at the same time? It must have something to do with my computer, since it's the only PC where I find this problem. I mean, the buttons work just fine, but for some reason it doesn't seem to regirster when they're pressed at the same time...?

Anyone else have any similar problems?

Help, anyone?

Thanks!
