Color Picker - Lost
I am using Photoshop CS5.1 and I recently updated my Windows 10 pro 64 bit.
I just wonder if it is the recent Windows 10 update a few days ago that had caused my color picker to be lost. After much attempt to relocate and resettings I only manage to get this one. So I just wonder if I should reinstall the PS to overcome this problem.
note: the Windows 10 update is not the 1809 but just the normal updates that comes on now and then for version 1803
the old faithful which was lost is as below.
