Most likely you have the two workbooks open in different instances of Excel.

To test, close one and open it again from the File-Open option within
Excel...

To fix the 'problem'
Try
Close Excel first and On the Windows Taskbar

1) Start-Run- excel.exe /unregserver -OK.
2) Start-Run- excel.exe /regserver -OK.

See the space between exe and /regserver

You might have to designate a full path to excel.exe (most likely C:\Program
Files\Microsoft Office\Office12)

In that case Start-Run- "C:\Program Files\Microsoft
Office\Office12\excel.exe" /regserver - OK

Note that quotes are required because of spaces in the path

When I want to copy data with paste special I used to have the option to copy
all and it would copy the entire format. Now however it is a different pop-up
window that gives me the options to paste it as an object, picture, bitmap
etc.

Does anyone know why this changed and how I can go back to copying the
entire format incl. borders etc? Thank you in advance.
