error changing number format

Gurus,

Before opening an OSS....thought I would ask.

I have a user that gets an error when trying to change the number format of a measure.

this is in 1.4.10

Error is:

StartIndex cannot be less than 0. Parameter name:startindex.

I cannot make this happen on my own computer.  So far I have not found an answer....even after a reinstall.

Any pointers here?  My first guess is something installed on this PC is causing the issue.

The error was present in the previous SP of 1.4 for this user as well.  But worked prior.

thanks

jim
