PD 13: windows keep resizing

Hello,

I updated to PD 13. I like to use my virtual machines in a window which is sized manually, so I can use a VM next to another window. Since 13 these windows resize to a small format, each time i start a VM, or even when bringing it to the front. This is very annoying, because everything whithin the VM window resizes, and makes icon change place.
I cannot find a preference to adjust this behavior.

Kind Regards,

Philip.

 

If possible, please submit problem reports taken before (when you resized a window) and after (when window is resized after reboot). Screenshot which shows window before could help too.

 

OK,

Screenshot_109 is after the window resized itself, screenshot of the original size cannot be uploaded because it is too large. I usually drag it as large as possible while retaining the Mac Menubar, not using Full screen. But it happens from whatever size I set the window.

I am using a MacBook Pro 15" retina (2015), with the latest Mac OS (10.12.6) and Parallels Desktop 13.0.0.

Philip.
