Unroute a segment causes an automatic rerouting

[Ro-prof]

I have checked but I could not find a related post.

I am making a design aiming to use stripboard.
In the beginning, I used some jumps for connections, but it became a little bit messy because jumps and components have the same color. Then I decided to you change the "jumps" for "top line" connections.

When I remove one jump by the "unroute segment' option:
1- an automatic rerouting in the related net is performed; and
2- the length of some lines are optimized; and
3- jumps are converted to "top line" segments.

1- Is it possible to block the automatic rerouting?
2- the same with the optimization?
3- the same with the jump conversion?

Many thanks in advance.

You can convert all trace vias to static vias. In that case, unrouting a trace or a segment won't affect vias.
To convert trace vias to static, right click on any trace via and select "Convert to Static->All Vias" from submenu.

Alex,
thank you very much.
I have tested it, and it was exactly what I want.
Not exactly easy to figure out without your advice
