I have a macro that copies a range from one workbook, opens another workbook,
selects a sheet and then pastes it. Part of the code looks like this:

ChDir "C:\"
Workbooks.Open Filename:="C:\Temporary.xls"
Sheets("Sizes").Select
Range("A3").Select
ActiveSheet.Paste

It used to work. I can say that what I have changed is that I created a
Change Event in the Workbook called "Temporary". Is it getting confused by
that somehow? Thank you for your help.
