CRXDE bug - properties tab slowly closes

[#1]

today an odd behavior started with the CRXDE properties tab. The properties tab on the home tab vibrates and slowly closes.

I'm running AEM 6.2 and Chrome latest version on a Mac.

The process was noticed after I just created a new component that extends another component. 

Any ideas on what causes the problem and how to solve it?

Check Zoom option of your browser. If it is not 100% crxde behaves likes this.

Thanks. The window was maxed on the Mac. Making it less than full screen solved the issue

There's also sometimes a problem where your properties tab in CRX/DE would not open. You will need to clear cookies, and that typically solves the problem.
