Yeah - I had lots of trouble, too, when the problem appeared.


Anyway, one question that remains is how to avoid the problem in the future.

Fast save will "hide" the fact that there is a problem, until the 16th. save (the full save). (The number "16" is from a previous version of Word - I didn't repeat the test with all versions available to me.) I would turn fast-save off. With today's fast computers, and the background-save feature, there is no noticeable delay in saving a document.

Another reason to turn off fast-save (both in Word and in PowerPoint) is that it will sometimes significantly increase the size of the file.

I am not sure whether the problem is caused by "fast-save" in the first place. I didn't have this problem recently, so I consider this at least a possibility. I work without "fast-save" for perhaps a few years now.


In my experience, Word can easily handle a document with 91 pages - or several times that amount. Problems appear, as mentioned before, if you have several graphics. (Better don't ask me what "several" means! - sometimes even very few graphics caused me distress.) But I never had the inability to save when the document had no graphics.


For large documents - and especially those that contain "several" graphics - it seems to me that the best strategy is to divide the document into chapters or something similar from the very beginning - for instance, each chapter a separate file.

Use a master document to combine the chapters for continuous page-numbering, and for easy printing.
