I just uninstalled build 1700 from my users and re-installed 1500. The main reasons for this step back :
a)Projection and projection transformation problems. The users use a lot x,y through find tool, a lot of times the x,y through GGRS_87_to_WGS_84 were incorrect
b)ArcGIS explorer crashes a lot of times when raster data is loading and we cannot send reports
c)Notes taken and opened in another software e.g. Google Earth were incorrect
