By the way, you can get the PDF-version of any file from google docks from "File-menu->Load to device->PDF" or in any other common format you prefer...
Very funny.
I said that the trashy popup message appears
almost instantly, so yes, it's possible and I even managed to go into menu File and expand it, but a
half-second time window to do so is just too short to expand other sub-menus. (I'm talking about the inside page-wise File menu not the browser's File menu.)
I also tried to "Stop" (as in opposite to "Refresh") loadning a website while and twice I saw some of the walkthrough content, but then clicking on Menus like File does nothing, unless the full page content loads (all those scripts load, along with the annoying non-closable popup message).
And it's File -> Download -> Save as PDF
[sb else gave me an alternative link, and that was helpful for a change]
