I am using 7.14.8 in windows and I noticed the "cp" command no longer automatically places the new solid on the screen. You now have to "e" it up there prior to being able to use it. It's not a big issue but it does add another step in the process and is a bit annoying when it had that capability for years. Still looking forward to a new windows version.
This is undoubtedly similar to the issue reported with analyze, cat, dbfind, and the 'l' commands (which were restored/fixed in 7.16.8). Thanks for the report.
