View Summary not working

SuiteCrm 7.8,.1
Accounts / Contacts - History - View Summary
Brings up a blank window.

Any ideas?

I confirm the issue. I just tried on http://demo.suiteondemand.com and, when you click a blank popup appears.

Confirmed as a BUG
Fixed for next version here: https://github.com/salesagility/SuiteCRM/issues/3079
