All of a sudden, I can't use the undo command for anything in InDesign. Could I have clicked something unknowingly that could have changed a setting? I am so confused! I never realized how often I used it until now. Example...if I resize something and don't like it, I can't click undo (or command+z) to change it back to the previous size. Anyone else had this problem? Any suggestions on how to fix it?
Reposting from another thread:
I suspect that this problem is not really file-specific or machine-specific, but is associated with processor usage/memory availability; just now I was working on a file and noticed I was down to only one undo. At the time I had lots of other applications running in the background. I closed everything and restarted, then did a test with a fresh inDesign doc, and I was able to undo 33 times (that's as many actions as I had executed in my test file.)
