Thank you for the information. It could possible that your AutoCAD might affect the functionality of Excel because you're running it at the same time. It may also due to not updating your Office 2010. In this case, we recommend that you install the latest Office updates first to make it updated. Once done, check if Excel keeps minimizing itself while using it.
We look forward to your update.
