how to change xsane from defaulting to full-screen window at 100% magnification?

I am using xsane 0.999 on Fedora 41; it used to bring up any new scan window in a 
reasonable size, but now is always 100% zoom in a full-screen window, and I see no way to 
change this default, only to change each window after each scan.

Possibly this is something that Redhat have done to modify xsane (xsane -v reports this 
package is modified from the original); I may have to contact bugzilla.redhat.com but the 
first thing seems to be there is nothing I can find in the online documentation nor the 
installed man pages (the -R option is not what is needed). I hope there is a way to 
change the default.

Any help appreciated,
