Turns out that this is not a show-stopper issue for me. Paint Shop Pro includes a menu item "End TWAIN Session" that can close the SANEWinDS dialog. So: this is a non-issue. Sorry for the false alarm.
Anyway, I'm seeing this behavior with both the x64 and x86 version of SANEWinDS. It's as though it's waiting for some kind of confirmation from PSP or from the saned server, but never gets it. Here are entries from the saned.log for two successful scans: one from SANEWinDS where the twain window hangs, and one from XSANE that does not hang. I'm not seeing much of any difference between the two.
It's ancient. Paint Shop Pro, version 7.04. 32bit windows app from 2001. Seems to work just fine with the native HP twain scanning driver for my scanner. But there's no network scanning with that, so I'm excited for SANEWinDS. It's communicating over port 6566 to avision:libusb on a Ubuntu box that the scanner is connected to.

After a successful network scan, the twain scanning dialog box has grayed-out "Close" and "Scan" buttons. The only way to continue is to kill the host graphics program calling twain via the task manager.

Eh. Just noticed that there is a new setting available in the conf file: \#set this...
