Excel Windows Different 2010 and 365?

[OaklandJim]

XL 2010 workbook opens with three windows configured (location on screen and size) as they were when the workbook is saved. XL 365 opens with three equally sized windows in the middle of the screen. Tried fiddling with Windows object and indexing but read somewhere that, for example, indexing window 1 accessed the currently accessed window not the one with index of one? Tried various ways to use filename plus window index but no dice. I'd love example of basic code to loop the three windows (one through three as they were saved) and resize them. Thanks so much for your assistance. Jim
