Email signature no longer attaches itself automatically to composed mail.

[Duploboy]

Hi,

I had added 3 or 4 external email accounts for each of 5 SugarCE users.

Created HTML signatures for each, all seemed to work correctly until I made adjustments to the signatures or created more than one signature.

Now, the signature is no longer being automatically used for newly-composed email.

It can still be selected from 'Options' menu but requires to be done with each new composition.

Does anyone know what may cause this behaviour and/or of any potential fixes? (Is there a cache I can clear, or something?)

Any suggestions would be appreciated, thanks.
