To reproduce:
1. Start with a script that has on mouseUp handler
Notice that available handlers doesn't include on mouseUp
2. Remove on MouseUp handler
Notice that available handlers doesn't include on mouseUp.
Bug: Would expect that available handlers to include mouseUp
3. Close script, and save
4. Reopen script, and now available handlers includes onMouseUp.

Hi Bill,

welcome to the forum!

I don't think this is a bug, LC just does not update the list "on keydown/up" nor on "on deletekey" etc.!
After deleting the mouseup handler in your script, hit ENTER once and it will re-appear in the list.

Best
