A couple of months ago, after an update, TaskSpace stopped worked properly with ConnectedText's floating windows, and so I stopped using it. But just a few days ago I got frustrated again with not being able to organise my floating windows across 3 monitors and contacted the TaskSpace developer about it. I should have done that in the first place, as he sorted my issue within a matter of hours and I'm a happy bunny again. TS seems to have come a long way since the OP, so here is a mini review/overview of things that have changed:
Dragging windows into it doesn't capture them...

There are now a few very handy shortcuts, including "move current window to last active TaskSpace" (CTRL+SHIFT+M), so there is no need to drag and drop even (especially useful if the TaskSpace window is on another monitor).
EDIT: bah, it doesn't group then in the sense that they mini/maximize together.
-urlwolf
TS can do that now. Another related option that has been added is "Always on top" or "Normal".
Looks like it only works on 32 bit win 7 ![Sad :(](https://www.donationcoder.com/forum/Smileys/fun/sad.gif)

There is now a Win7 64 -bit version as well.
Maybe that's the reason it's free ![undecided :-\](https://www.donationcoder.com/forum/Smileys/fun/sleepy.gif)

It has moved to a freemium model.
when moved between different monitors (with different resolutions and sizes), the docked windows can get a bit messed up, so need manual rearranging. -dr_andus
That's been resolved.
One needs to be pretty careful during installation though not to install all the adware stuff...
-dr_andus
Looks like that's no longer there, now that it has gone freemium.
There are a few minor issues that the developer is still looking into for me, but overall this is coming together nicely. But I've only been using it with CT, so YMMV. I recommend getting in touch with the developer if you run into any problems, as he's very responsive.
