  Hi,

  We are using winforms edition(version 4.0.20201.416) of the grid. When moving the form window when the grid is busy doing some operation. Grid gets distorted as shown in the attached document. We get the following exception in the application:

  Global exception occurred in Schedule Editor:
  
  System.NullReferenceException: Object reference not set to an instance of an object.

  Hi Kshitiz,

  This is very strange and we never came across this kind of issue before.
  
  If you can replicate this in a small sample then please attach it here so we can look into it.
