First, if I am using the wrong term "roll up", that may be why I am not getting results from my searches...
With both FF and Chromium on Fossa64 I can put the mose on the title bar and rull up to "window shade" the prograam. Once again, that may not be the proper term.
For some reason when I fiddle with the Opera browser it does not work. Is it something I can enable somewhere? I do have Opera up to date. It is pretty slick that the Browser downloads a .deb so it is a easy upgrade. You do need to open a roxfiler window though. If you try to install from the downloads button in the browser it gives you a password request during install.
If you simply find your downloads folder via the desktop home button you can click and install as expected.
Thanks for your time.
