I have an Excel application that contains a number of buttons that have code
behind them which opens various documents (word docs, powerpoint
presentations and excel workbooks). The issue that I have is that when the
application is promoted to Internet Explorer I can only open the word and
p.p. items and not the excel w/books.

the usual :
Workbooks.Open "file and path name"
does not work.
Any solutions out there?
Cheers Damo
