I'm having a problem with netinstall in the past couple weeks, coinciding with upgrading to more recent releases (I am currently running netinstall 6.42rc49, and still see it).
The syndrome is this: the router shows up in the window as "Ready," I select it, choose the software, and click Install. Netinstall briefly flashes "Sending offer" and "Installing," both so fast you can just barely read them, then the word "Ready" disappears from the router line and it grays out. It comes back to "Ready" approximately five seconds later, at which time you can repeat the same procedure and obtain the same results. Quitting and relaunching netinstall doesn't fix it.
Is anybody else seeing this? Does anybody know how to cure it?
