Sorry about that. Looks like this is a bug in 3.8.99 We've fixed it in v4 but unfortunately don't have plans to do another 3.8 release as we are focused on v4. Also we've hit 3.8.99 so we'd have to do a 3.8.100 release, a version number which doesn't look so nice. :grinteeth:

I knew the answer would be exactly like this , I was suffering from this bug the day the version came out.
and everyday wanted to post a thread here, but version name 3.8.99 suggested that there would never be any iteration on the v 3x

p.s. the bug is really painful

I can imagine. What we could do is re-release 3.8.99 with the fix. I hate doing such a thing, but we've done it! Delete the update file named 3.8.99 from your updates folder (or run Spine with -f or `

force`) so it will download 3.8.99 again, then you can again enjoy deleting your keys by double clicking!
