I can see where it might be a big problem if there are file names, sheet
namen or other names that are common to both versions of Excel or between
concurrent instances of the same version.

Some of the macros I have written sometimes do not function correctly
if another instance of Excel is open. The other instance usually also
contains macros that may or may not have been executed. I thought I
read somewhere that this is a common problem but a recent search has
not turned up anything. Does anyone know of a solution to this or
any
tips to minimise the chances of this happening? I am using both
Excel
2003 and 2007. Thanks.
