We have a set of spreadsheets that contain scrollbars added in developer mode. Clicking these scrollbars changes a value and a diagram in the spreadsheet.
Suddenly these do not work. The mouse cursor changes to a multiple arrow symbol when hovering over the scrollbars- as if Excel is in design mode. Toggling design mode does nothing, and I have tried enabling lax security settings.
The documents in question work fine on other machines.
I have tried repairing the Office 2010 installation. Any ideas?
