[Micha]

Can't seem to delete any tracks anymore in PCBNew.

It completely crashes, the Visual Studio Debugger shows the following (I just coppied all information I could find that might be useful)

Unhandled exception at 0x00007FFF653DEB78 (ntdll.dll) in kicad.exe: 0xC000041D: An unhandled exception was encountered during a user callback. occurred

Unfortunately due to non-disclosure I can't attach the file, I am however willing to send it to one of the developers personally in good faith.

Are the tracks you are trying to delete locked?

[Micha (pmic)]

I don't think so, I tried to unlock them to be sure. I did however do some lock toggling on a larger selection. Currently trying to find out if a small portion of the tracks might still be locked somewhere, as the complete file seems to be corrupted by this.
As soon as I delete a track everything crashes.

Is there some way to tell if any locks are still in place, perhaps when looking at the kicad_pcb file with notepad++?

[Micha (pmic)]

Allright, I fixed it. I found out that " (status 40000) " means that a track is locked. Removed all by hand in the kicade_pcb file, and the file works again. Hope I didn't destroy anything by accident, but it looks good.

Would like to change the bug report to "Crash when trying to delete locked track".

[Nick Østergaard (nickoe)]

if you are able to reproduce this issue easily on the design you have now, you can try the 5.1 builds, it should be fixed there given it is the issue about deleting unlocked tracks.
