I too have a bathroom window that sweats profusely. The window is single pane aluminum, and although new, it is inexpensive. The bathroom has a ceiling fan that runs 24-7 year-round to keep the air circulating. That room is heated by a small oil-filled radiator, but not cooled in summer; average humidity here runs about 60 percent. We all make sure the window is opened after showering, etc.
Just a few degrees difference in outside/inside temperatures produce so much sweat on the glass and aluminum frame that we keep a handtowel handy to keep the window wiped down. (The toilet tank was also dripping sweat, but we solved that problem with a terry cloth cover.)
Of course, I'm concerned that the window opening will rot away. I'm thinking of removing the window and installing a line of flashing all around the frame and then reinstalling the window. Although we'd probably still have to keep the window wiped down, the flashing might help protect the wood.
Does this sound like a good idea? -- Or is there any reason not to flash? Thanks for your thoughts on this irreversibly sweaty bathroom window.

As silly as this may sound, your window is doing its job. But the window is not designed for it's enviornment. The only "fix" will be to replace it or add a "storm window" to the outide (attached to anything other than the window, creating a thermal barrier)
Lets start with the premise that windows don't sweat they collect condensation. I say this because once you focus on that principal, you will probably answer your own question.
But hey, thats what I'm for. so here goes my advice.
Replace the cheap(inexpensive) , single pane aluminum window. Aluminum is a conductor. Glass is a conductor. Your window is creating the perfect minature storm front you know the cold from is meeting the warm front and rain is expected. Temperature ( inside and out) and humidity (inside) co mingle in dasterdly ways, with dasterdly results.
My advice is a double pane, wood or vinyl replacement window or an aluminum with a built in thermal barrier that separtates the inside metal from the outside metal. or
add a storm window to the outside.
Good luck
