Thank you so much for the information and the hotfix of Spire.Doc!
I just tested the hotfix and all issues seem to be resolved. I am very happy that your developers were able to solve these layout problems (to be honest, I didn't expect the problems could be solved).

Both Spire.Doc and Spire.XLS are great!
They helped me write a tool that I use in my work for the automated execution of documents. Thank you very much!
I am very happy with these libraries and I will definitely recommend them to my friends.
Best regards, Jacek from Poland.

I'm waiting for a confirmation from my superiors to buy the license. But we already finished the tests with the Spire.Doc, and it works perfectly!
We are very excited to start to work with it, because it fixes a lot of bugs that we have using the Microsoft.Office.Interop's dll.
I guess that I'll probably have the confirmation in the begin of the next year.
