Cognos 10.2.1 FP6 - cannot paste in reports in IE11?

hello,
We upgraded from 10.2.1 to 10.2.1 fix pack 6. --> Now this works. I did F12 a couple of times and swopped between Edge and 5.

Menu > Edit > Paste dosn’t work in IE 11. In Crome I can paste within the same report but not between different reports.
Any ideas?

In IE 11: Can’t copy/paste in the same report and not between reports
In Crome: works to copy/paste in the same report but not between reports.
In Firefox: works to copy/paste in the same report but not between reports.

br, Maria

thx for the feedback!
