Creating parts with movable schematic elements

Hi Peter,
Thanks for this!
Yes, the search was working on Win10 for me perfectly until today.
It happened whilst I was trying to recovre that sketch.
I had just used it succesfully then next time I tried it the tab was there but it was broken. I reloaded the program and the tab was gone.
This fix sounds like it could cause even more problems if it corrupts my sketches.
I haven't tried opening any others yet but I shudder to thinkj there could be problems with devices I have already built! Oh no! I will make do without search for a while
Cheers, Kevin.
