I can verify having this same issue with all windows. For example, right now I have 4 Windows Explorer windows grouped. If I have the group maximized, then move it to a different monitor while maximized, it will remember that monitor per tab.

Steps to reproduce:

1. Group multiple windows (any windows seem to do it).
2. Maximize the group if not already maximized.
3. Click and empty area of the tab bar, drag to another monitor and make sure to drag it to the top of the screen (where you get the animation indicating it will maximize on release). Release the mouse button.
4. Click one of the other tabs, for windows that were originally on the other monitor.
5. The whole group will jump to that other window.
6. Clicking the tab that was moved to the new monitor will jump the whole group back to that monitor.

I actually have 3 monitors - all the same resolution (1920 x 1080), and all the same model.
Two are using DVI cables, one is HDMI.

(Sorry if there are any typos, I just ran into another bug where it seems to have conflicted with Chrome, and I can only see half of this window.)

Thanks!

I have 1.0 and I can confirm this problem still occurs. And the reproduction steps above reproduces on my machine. Of course, I restarted and confirmed the version.

Thanks! I probably should have created a new post for this, I just assumed it was the same issue.
