I run a shelter for abused and neglected children. I have a spreadsheet that I paid to have written that we use as a database to track referrals, admissions, and discharges. The spreadsheet has a button that opens a user interface window that allows the staff to input the information for these three functions. We use a single file on a computer in the staff office with other computers having access to that file via a Windows 7 network. Recently, that button has quit working on the computer in the staff office. The button cannot be left-clicked or right-clicked. It's as if it's not even there. This is also the case when the file is accessed from the computer in the Assistant Director's office. However, when I access the file from my computer, the button works, as it does when opened from a laptop that has access to the file. All of the computers are running Windows 7 and Excel 2010. I've ran updates, check protection levels, etc. but can't determine why the button no longer works. Any help would be appreciated.
