Magic Mouse wont close program or window when I left click.

Question

Hi,
so I bought me a new set up iMac i7 with among others the magic mouse 3 months ago.
Not everytime but quite frequently when I try to close a program or any kind of window, by left click the red button on top left corner, it wont work, nothing happens.
Then I have to click somewhere outside that area and then go back to the red close button and it works.
This is also present sometimes when I want to close a tab in safari by the tab cross-button.
Anyone who has an idea of what the problem might be?
At a first glance I thought it was a software bug, since it work when I click outside the red close button and then go back and it works.
When it stops working it doesnt matter how many times I try, it just wont do until I click once outside the area.
I also have a track pad but it works flawless!
Thanks in advance for any hint into right direction!
regards - Peter

Do a malware check with some malware scanning programs on the Windows computer.<br />
You need to scan with all programs because each program detects different malware.<br />
Make sure that you update each program to get the latest version of their databases before doing a scan.<br /><br />
