Try this:

Position the mouse on the grid. Click righmouse: the dialog should appear, choose 'edit' there. Around the grid you will see a colored border and then you should be able to work as you wish.

>Hi all,
> I have a strange one that I haven't run into before. I have a grid with 9 columns. The form has been edited by 2 different people. We have never had a problem with this before but I now cannot use the mouse to change the column size or drag the columns left/right by clicking on the column header. When I move the mouse pointer over the column headings it changes to the pointer only instead of the big down arrow over a heading or the double horizontal arrows over the line between headings. I was able to change the column size in the property box and I can use the mouse to change the size of the grid border. I am worried that the grid has become corrupt.
