Krondor seems to be easy to run in a window, since it's a dos game, running on an emulator. But what about Antara? It's a Windows game as far as I'm concerned, and I don't see any options to do so.
Any ideas? or is there no solution?

I seem to recall a way from when I had the CD version of the game years ago, but i'm not sure about GoG's release. The game seems a little too unstable for most to be able to successfully run in a window, although there are some threads about it further down. I'm looking for help finding a chest for a side quest and I'm about to pull my goddamn hair out. :/
