A family of Microsoft word processing software products for creating web, email, and print documents.
That is definitely not the issue. I am not running Office 2010 and 2013 side by side. Office 2010 was completely uninstalled and removed before I installed Office 2013 and ran into the above problems.
In the meantime I also had the chance to test this behaviour on another system: Installed Office 2013 on a clean system and worked with the files I have had problems with on my system. The clean system showed the exact same issues: Slow saving and pasting into long documents.
I am experiencing the exactly same problem as Silbenhai. How come this issue is invisible to experts from Microsoft??? I got two computer. Saving a large file is fast in word 2010, but very slow in 2013. I notice that file saving can active a function of "searching for issues", which can be seen during file saving process by going to "FILE" and click on "info" I wonder if the slow saving problem is caused by this "searching for issues" ? I am expecting solution, since I am working on a 300 pages long document and slow-saving is definitely not a good experience. Thank you very much.
