Each crash to desktop on Win 10 64-bit shows Dropbox updater 32-bit had just auto-launched. As Win 10 MS Store is now providing this game as XBox-emulated, this may be Dropbox killing the XBox runtime emulator and not TSW3 per se. Regardless, Dovetail should ask Focus to give both Dropbox and the MS Xbox team a heads-up. Of course, this could be TSW doing DASD rd/wr without checking resource avail or in a loop assuming res avail. I do not yet see a correlation within the game activity from UX side. Because i check running processes before and after a fragile program in the Win10 Task Manager, this crash correlation is likely indicating a cause of this runtime ABEND. thx r retired sw eng back in Canada
