If you have any issues with the SimpleView viewer within SimpleIndex not displaying properly or the grid size being off you can reset it by doing the following.
1. Go to the Registry by searching for regedit
2. Locate this folder path:
hkey_current_user\software\vb and vba applications\simpleindex
hkey_current_user\software\vb and vba program settings\simpleindex
3. Delete the SimpleIndex folder from that path, which deletes all the saved user settings and reverts back to default.
