SAP GUI 7.7 APO dataview changes in display for negative values

Hello,

There was a switch in the used SAP GUI version from 7.6 to 7.7. Unfortunately this resulted in a change in the display of negative figures in the standard SNP data view. Previously negative values are displayed in RED but with SAP GUI 7.7 it is just BLACK. Is there any way to revert to RED?

Any ideas?
