Crystal reports XI: Change x-axis labels font size.

Hello,

I've just received a set of .rpt Crystal Reports files from an external developer, and I have to make some "formatting" changes. I'm not very experienced with Crystal Reports. I've found what I think it is an odd behaviour: I've got a sub-report which have a lines graph with numeric axis. I change x-label font size from 13 to 5 and I save the rpt file and close the file. I check that the rpt file in fact is changing it's modification date. When I open the rpt file again, I find that the x-axis font size is back to 13!!

As I didn't find a solution, I installed Crystal Reports in another PC, and there, x-axis labels were right sized. So I checked CR version, and in the machine that worked was 11.5.8.826, and in mine (don't work) 11.5.9.1076. Next step was upgrading the machine that worked with Service Pack 3 of CR, and then, x-axis labels became wrong sized as in my computer.

I realized there is a newer service pack (4) for Crystal Reports XI R2, and I tried installing it, but still the same issue with x-axis font size.

I hope you can give me a hand.
