CorelDRAW Graphics Suite 2018 freezes while completing the edit of a Powerclip

Hi, i am using Corel from Version 5 till date.

I am facing this problem only from X7 and i have installed my new "CorelDRAW Graphics Suite 2018" today, and this same problem is existing.

I am able to edit a powerclip,
but when i have to close or complete editing my powerclip,
either the machine takes a long time or freezes 
indefinitely.
Is there a solution for this issue, since i use powerclip extensively.
