If you delete the row, don't increment the loop counter (or possibly
decrement the limit condition, but I'd try not incrementing first).

			if(curCB.checked == true)
			{
				row =
table.getElementsByTagName("TR").item(x);
				tbody.removeChild(row);
				x = x - 1; // decrement x to counter the x =
x + 1 below
			}
		}
		x = x + 1;

OR
			if(curCB.checked == true)
			{
				row =
table.getElementsByTagName("TR").item(x);
				tbody.removeChild(row);
				numrows = numrows - 1;
			}
		}
		x = x + 1;
