I use Microsoft Office 365 and for windows 10 x64 which is lasted update from my company side. so the most of problem when I use Microsoft excel in my laptop is that once I open excel file for edit my information and use touchpad or mouse to score task bar in excel file, the application will be hang state.
the work around from my side must be close the application and re-open it again and then use the cursor arrow key board to move pointer instead.
so on this problem, that is not comfortable to use Microsoft for me
it says everything
