Non-deterministic Behavior with CChartObjectButton.State() method - bug??

[kisiel]

To Development team of MQL5,

I don't understand why the hell the State() method shows non-deterministic behavior when I use it to check if a CChartObjectButton is "pressed" or not!

Wenn I press both buttons and move both lines, it looks like this:

When I wait some time and do nothing it looks like this:

What's wrong?? Thanks...

Here is my code:
