I just figured it out, just in case sb ever needs an answer and doesn't find one

One needs to change the z-index in CSS file of #btnShowDlg to this (not exactly)# 638746and then the fields within the modal preview are editable.. No need to change anything else :)

Just go to your css file, locate #btnShowDlg and either change or set z-index:638746;
