Help please to edit a component in inkscape and then use it

I am not adding 'new' terminals , you added them, I assume, with inkscape. I moved them back to inkscape and just moved the teminals around to fit the contacts on the silk screen.
I will have to try your 7.zip the next time I do it.
It knows I have altered the file name 'cos it remembers it and tells me it is already there if I try to load "an altered " file. Do you know where it stores this info so I could clear it and use the numbers from 1 again?
