Double warning message

[PhilipWaldman]

When you enter an invalid input for some properties two warning windows pop up. These windows are identical and perfectly cover each other so it is easy to miss, but when you move the top window you can see the other one. Some examples of properties where this happens include: "Address Bit Width" for the RAM component and "Number Of Inputs" for any of the gates that have this properties (e.g. AND Gate, XOR gate, etc.). But this does not happen for the "Data Bit Width" and "Data Bits" properties of the RAM and gates, respectively.
