Originally created by @glitch100 on GitHub (Jan 15, 2020).

I assume this is to do with the TabViewItem.CloseRequested Event not being respected properly or some sort of bad subscription to it.

For what it's worth I would be happy to take a swing at this one if you aren't going to prioritise it but would need some pointers. CPP isn't my main, (C# is) but I suspect the event that is required or used somewhere might be in the CPP modules.

Environment

Windows build number:  Win32NT 10.0.18362.0 Microsoft Windows NT 10.0.18362.0
Windows Terminal version (if applicable): 0.8.10091

Any other software?
None

Steps to reproduce

  • Open Terminal
  • Add new Tab
  • Use Mousewheel to second tab
  • Crash

Expected behavior

New tabs being closed don't cause crashes

Actual behavior

New tabs being closed by mousewheel cause issues
