Can msTimer2::set() - be called more than once in a sketch?

I'm having a problem getting subsequent calls to msTimer2::set() working.

This thread seems to indicate there is a problem with subsequent calls to ::set()

Are others having this issue?
Is there a better timer library or better workaround?

I'll post my code once I know if there is a problem with mstimer2- in general.

Thanks
