Thanks for the suggested help. As you suggested I have searched for and
found “XLSTART†in 2 locations, but both folders are empty with 0 bytes.
I have also looked in Excel > Tools > Options > General, and the “At
start-up open with†box is unchecked and there is no entry in the box
I do not know how to tell whether I have an alternative Startup directory
set, but I have searched the PC and found a number of Startup folders, none
of which contain anything except a “desktop.ini†file.
Unhappily the problem remains. Is there anything else that I can do, please?
