Go to card has become slow

[Bob Sneidar]

Richard, I can verify that my mainStack is pretty big in terms of objects and code. When I create a standalone for Windows however, it breaks out all the substacks into individual stacks, and the saving just the mainStack in a Windows standalone still takes longer than saving the entire Mainstack with Substacks on the Mac. 

As a countermeasure, I suppose I can work on getting all the scripts I can moved into script only behaviors. I still make extensive use of Datagrids however which have a lot of objects. Most of my substacks have multiple grids and the main stack has 7. 

I will also say that I have seen a considerable speed difference between Mac and Windows when expanding a fairly large zip file contains lots of individual files and folders (copier firmware to be exact), so I do not thing the issue is with the LC engine, or at least not entirely. It’s so prevalent that I don’t even use windows to expand these files anymore.
