TCW Deluxe 21.2 64 Bit
It took me a while to realise I couldn't copy in place unless I had any form of hidden line switched off, but today it has disappeared from my edit menu and won't come back whatever I do, even if I create a brand new drawing with everything at default.
The help (from February) claims it isn't in the 64-bit versions which is patently untrue as I've been using it for a couple of years.
Is it possible there's some switch flicked I don't know about?
The only odd thing I've done is drag and drop a PDF to import it, but ALL files are affected.
Please help, producing any drawing with repeating elements is next to impossible without copy in place as ordinary copy loses every transformation.
