Thanks for the reply, and for confirming what I thought would be the case.  I have left feedback several times before now, but since these product requests are dealt with on a priority basis I guess not many other people see it as a problem.  It's just really annoying because a minor change to the definition of that particular field within the database and the data validation on the form would solve it instantly (once it was compiled and rolled out as an update, of course).

I already use the Memo field as an alternative, but it isn't very good as a solution when it comes to searching for transaction references.

Thanks anyway,

Angus
