I have workbook that is shared by many people through a secured citrix
server. We encounter many issues with this workbook, i.e. it crashes, data
validation is lost when we try to copy and paste, generally it causes us
issues.

Is this down to the fact that it is a shared document and does not like more
than one person using it at a time, or might it be to do with accessing it
through citrix.

Any suggestions would be greatfully received.

Thanks
J
