I bought Bruce Waltke's book Old Testament Theology and his Logos Mobile Education Course for the same subject. I found that that the Logos book is heavily marked with yellow highlight for the suggested readings in the mobile ed course. In Logos 9 I could add my own shadow text highlight overtop the yellow highlights. I found in Logos 10 Android that if I try to do the same thing the problem crashes. I just checked on my PC to see if I could recreate problem. I found there was no yellow highlights, just my shadow text highlights. I did go to program setting and turned off highlight but then I can't highlight at all. Ang suggestions?
