comments issue
 

i have a user with a very large spredsheet and when ever she tries to edit or
a delete a comment on the spreadsheet it will crash excel, it doesnt give any
errors and excel just stops responding in the task manager.

this only happens on this particular spreadsheet and it will let you
edit/delete a comment once but if you try to edit/delete another comment it
will crash the app

any ideas what could be casuing this ??
