Let's track the issue with minimized in this thread, just so we don't have it in two places:
Spine non-responsive after Alt+Tab full-screened [3.8.98]
@DenisZ We've uploaded a new launcher. If you download and reinstall Spine you'll get launcher version 3.8.99, which will properly prompt for you to update when there is a new version. Sorry again for the trouble!
We have also prepared a 3.8.99 editor version. It is ready for use, but hasn't been released yet. Would you like to try it before we release? To do so, run Spine and in the settings dialog click Other...
and type 3.8.99
. Alternatively you can run from the command line like this:
spine -u 3.8.99
It would be great to hear from you that the minimize problem is fixed before we release it for everyone.
