HI
In my project there are lot of NETs and after routing ...I changed number of 64 tracks color .
After that I had DRC error due that I started editing track and it takes a long time to editng tracks .
Then I changed 64 tracks color to default and then I started again editng now Its working well ....
(please note If this bug report Is not undestandable please reply)
Thanks
