The Clipboard functionality was changed for various reasons to to with improving Excel formatting on cut and paste (see the What's New section in the Help.)
However you can specify that you wish to use the V7 methods by using the Options for Monarch V8.
Options > Export and Clipboard Options > Clipboard should provide you with the control you need.
Not sure about the default folder display question, it's not something I have ever been bothered about. But my guess is it picks up the default display format last set for the folder it is accessing (mine seems to) which may or may not be a new folder for V8 depending on how you set up your system post installation. You may need to set the preferred view using Explorer I guess.
Hope this helps.
