Obviously, you are not handling intuition messages properly. Make sure
that your task has processed _all_ messages before going to sleep:

	while(1) {
		Wait(1L << mp->mp_SigBit);
		/* note this loop! */
		while(msg = GetMsg(mp)) {
			/* copy relevant fields, e.g. */
			class = msg->Class;
			code = msg->Code;
			/* ... */
			/* here and now! */
			ReplyMsg(msg);
			switch(class) {
				case GADGETUP:
					/* etc. */
			}
		}
	}

Otherwise, remaining messages may not be processed until a new one arrives.
This will cause the "offset" you encountered.
