Bug Report: Alt tab inserts tabs in to cygwin terminals

[Zarquan]

I use cygwin to run experiments on protocols on Windows using bash
scripts.  I often am running multiple programs that interact with each
other, so I alt-tab between the consoles.  Unfortunately, when I alt-tab to
or from a cygwin console, it adds a bunch of spaces to the outputs, which
is annoying to deal with.

It is behaving as though I am pressing tab in the console, which I
technically am, but it is intercepting the Windows hotkey.

Is this a known problem?  Is there a solution?
