I have edited a symbol and just noticed that the new pins have different =
size text for pin numbers than the previous pins.
I don't see any way to change the text size now.
1.  Select the symbol.
2.  Right click -> down symbol
3.  Double click on the text and change the font size using the dialog box.
4.  Save
5.  Right click -> up
6.  Delete the symbol on the schematic and then reload it.
I have this sinking feeling that I have to redraw all the pins.
Is there a better way?
Please let us know if this works for you!
