The MouseButton1Down event does not work for all clicks

[DanielLozovanu (FedoraMan)]

1. What do you want to achieve?
   I want to detect if the button is pressed.

2. What is the issue?
   For some reason the event does not fire everytime i click the button. And if i click only once it does not detect the click

3. What solutions have you tried so far?
   In this video i am currently spamming the button but in the console it prints a few times.
   

I tried to disable every GUI instance because i tought there was another Instance causing this issue.

-- SHOULD PRINT PRESSED WHEN THE BUTTON IS CLICKED
script.Parent.MouseButton1Down:Connect(function()
	print("PRESSED")
end)

Ok i fixed it. I found out that on the backgroud there was a TextBox that i scripted to always stay focused to. This TextBox was the issue all the time.
