It's still doing it for me but not every single time, but most of the time. I have a floating toolwindow all by itself. I'm sometimes adding a file from a sub-folder that isn't part of the project already, and sometimes a file in a folder that already has several siblings - it does it for both. I have toolwindows set to hide when slick loses the focus. In the file open dialog I sometimes double click and sometimes click the open button - it goes wrong for both. The files are slick C source *.e.
It doesn't seem to go wrong if I dock the toolwindow.
