Thanks for your response. It hasn't happened recently (since 
I updated the new field for all issues). The last time it did 
happen, I found that I could click the back arrow (on 
browser) when the template error page displayed and try 
clicking submit on the same issue again. This time there was 
no error (so I didn't need to retire the issue and re-build it) 
but all of the history had disappeared. 

I am thinking about migrating data to sqlite - is there any way 
of also transferring the history across?

Thanks again,
Paul

P.S. I have to say that roundup is an excellent application - 
we use it quite a bit in our company. Thanks for all of your 
work!
