I have to open an Excel file twice for it to actually open.

I have the same file both as an xlsm and xlsb, when I open the file, some process takes place then the Excel flash goes empty.  I double click the file name again and a recovery process takes place and I have two files on the screen, a "repaired" file and my original file working perfectly.   I have tried a "saveas" for the "repaired" file, but it behaves the same as the original when I open it.   I have searched for a way to correct whatever triggers this behavior, but don't know what it is.   This file uses classes for a binary tree to process the data in the sheets and create an ordered summary.
