What steps will reproduce the problem? 1. start a window with an unique name/class etc 2. unmap the window (e.g. hide it) 3. do xdotool search --onlyvisible --name "Windowname"

What is the expected output? What do you see instead? I expect to get no output, but instead I get the windowid of the searched (invisible) window

What version of the product are you using? On what operating system? 1.20100302.2713-1 on arch linux

Confirmed. I'll work on a fix.

Fixed in svn r2718

I'm going to put some more tests in to catch things like this, then I'll put out a new release.

Thanks for the report! :)

This should be fixed now in the latest release. Let me know if you see problems :)
