Hey guys, first post here.

I have a slight problem with my camera right now. When I press the right or left keys (A/D), the screen jumps in that direction(by a lot more then just the key press), movement goes as planned, and when the key is released the screen jumps back to where it would've been. Here's the relevant pieces of code:

The message loop:
while( msg.message != WM_QUIT )
			{
			   if ( PeekMessage( &msg, NULL, 0U, 0U, PM_REMOVE ) )
				{
					 if (msg.message==WM_KEYDOWN) OnKeyDown(msg.wParam);
					 else if (msg.message==WM_KEYUP) OnKeyUp(msg.wParam);
					 else{
						 TranslateMessage( &msg );
						 DispatchMessage( &msg );
					  }
				 }
			  
				 else Render();
			  }

void OnKeyDown(WPARAM key){
	 switch (key){
		  case 0x41:
				 ak=TRUE;
				 break;
		   case 0x53:
				 sk=TRUE;
				 break;
		  case 0x44:
				  dk=TRUE;
				  break;
		  case 0x57:
				  wk=TRUE;
				   break;
		   default:
					break;
	 }
}
void OnKeyUp(WPARAM key){
   switch (key){
	   case 0x41:
			  ak=FALSE;
			  break;
	   case 0x53:
			   sk=FALSE;
			   break;
	   case 0x44:
				dk=FALSE;
				 break;
	   case 0x57:
				wk=FALSE;
			   break;
		default:
				break;
   }

}

if (ak==TRUE) EyePt-=sideVector;
if (sk==TRUE) EyePt-=CurrentView
if (dk==TRUE) EyePt+=sideVector;
if(wk==TRUE) EyePt+=CurrentView;

I'm working on implementing a camera class, but right now I'm very confused as to why my camera jumps whenever the A/D buttons are pressed. SOrry for the messy coding.
