[xcrysden] Error: grab failed: another application has grub

[Masood Yousaf]

Dear Xcrytalden community members.

I got this error while Xcrytalden was calculating electron density for contour plots. 


Error: grab failed: another application has grub

I have two queries. 

what is the effect of this error on calculation ?
How to remove this error ?

Thanks in advance.


Best wishes
Masood
