This is note a serious bug, just very annoying (as usual with Recorder!)

In the Document Entry panel, Volume, Part and Number fields will only accept numbers this makes it impossible to correctly enter many of the Royal Ent. Soc. keys which include letters in the 'Part' e.g. Volume VIII Part 1(a) - key to Cynipoidea - I assume the datatype for Part needs to be changed to TXT rather than Integer

Also it would be nice if Volume numbers could be entered in Roman Numerals (or displayed as such) - this seems to be a common practice with journals (see RES Key example above)
