I have an Excel application that I have made accessible to my department via
a website visible only to my domain. The browser itself opens from within
another application, access to which is passworded (hence restricted access
to Excel application).
However the excel app behaves very strangely, crashing unexpectedly, not
closing completely which gives - unavailable for editing - messages when
next opened.

Does anyone else have a similar experience?

Website is created and published in MS FrontPage. Excel version is 2003.
Host application is Omnis 7 client.

Many thanks,

Matilda
