[Q] \dot over \overline

[Bor-Lin Shyu]

Hi,

I want to do this in lyx:

\dot{\overline{\epsilon}}

I tried to input the above sequence in lyx, but when I save it to .lyx
file, it becomes:

\overline{\dot{\epsilon}}

I corrected it by a text editor in the .lyx file and load it 
back to lyx and then save it in lyx, the \overline is again outside \dot.
Any suggestion on how I can force \dot outside \overline?

Thanks

Borlin
