Prevent Mouse Click From Affecting Ado Data Transfer

I'm using code based on the following post: Add Borders To Cells Of Spreadsheet From Access. That code was developed for a relatively small recordest. I am using the same coding style to transfer a recordset that has roughly 2000 records in it. Since this is all taking place over a network there is a period of time (about 15-20 seconds) where Excel is open and the user is watching the cells get populated from Access. If, during that period of time when Excel is open, the user clicks in a cell during the population of data, it stops the process and causes an error on the Access end (Error 50290: Application-defined or object-defined error). Is there a way I can prevent user input (perhaps prevent signals from the keyboard and mouse) until after the data has been transferred? I know this is a long way to do a TransferSpreadsheet command but I like the way the column headers get formatted as well as the column sizes. I also think it's pretty cool to watch the data populate as it goes.
