When I double click on a grid in GL to change the grid parameters I change the setting, click "ok" and the change happens until I leave that screen and come back to it: then the changes either haven't taken at all or come up with some entirely different parameter.
How do I keep the changes I want?? If I remove a column that seems to take but not the parameter changes.

GL Version?
What "grid parameters" are you changing? The fields being displayed? The field names?
Is everyone logging in with a different User ID?
