Just fixed a bug affecting string controls such as 'project name' and 'chart y axis'. The user wasn't able to change the values for these fields due to a check for isNaN (is not-a-number) which I put in a couple weeks ago.
Checking for isNaN was supposed to apply only to integer and float fields and ignore letters entered in those controls. Unfortunately, I didn't test well enough, the test was ignoring letters in string controls as well.
Anyway, sorry for the inconvenience! And please me know if you see any other problems
