Tools/Options/Grids.  I set the font size to a larger size.  The new setting seems to take affect in some grids but not others.  I have experienced this on multiple computers with different databases.  I also notice that on the grids that keep defaulting to a smaller font size (the size I do not want), that the word "item" at the very top of the grid is also in small font.  All of these are grids I just created before changing the font size setting, they are not default grids that come with the program, so it's not like there should be any grid specific setting on the grid that is over-riding the setting under tools/options (assuming that such an over-ride feature even exists).

 

Thanks
