Jim Monson Posted May 25, 2017 Share Posted May 25, 2017 After working intensely in a 300+ mg AD doc, certain AD functions no longer work. Quitting AD and bringing it up again solves the problem, and AD always remembers what I had just done (bravo!). I'm working with a MacPro with 24g of RAM with nothing else up except Mail. Does AD only access a limited amount of memory? Is the problem that its Undo remembers everything I've done in the session since I am manipulating many layers with hundreds of object? It may simply be a Mac memory problem. No big problem. Just wondering what the cause might be. Quote Link to comment Share on other sites More sharing options...
Staff Callum Posted June 1, 2017 Staff Share Posted June 1, 2017 Hi Jim Monson, While its hard to say exactly what the cause might be you could try changing the settings you have for the Performance tab of your Preferences. Particularly the first slider for RAM usage. Please let me know if this changes anything. C Quote Please tag me using @ in your reply so I can be sure to respond ASAP.

Gear maker Posted June 1, 2017 Share Posted June 1, 2017 Jim, this may sound crazy but I have found the same problem and limiting the undo limit to about 250 seems to alleviate the issue. I find 250 is more than enough undo's. Let me know if it seems to help your issue. Quote iMac (27-inch, Late 2009) with macOS Sierra Link to comment Share on other sites More sharing options...
Jim Monson Posted June 4, 2017 Author Share Posted June 4, 2017 Thanks to you both. My RAM was at 24g (my limit) but I had not noticed that my undos were in the thousands, totally unnecessary. I've lowered them to 250 and that should help. I'll try to remember to let you know, although when something is working I tend to forget.... The AD blog is a tremendous help. Much appreciated!
