B6 Win7x64: CPU pegged and user input frozen when tab is dragged out of window

[mako]

This happened in both Beta 5 and Beta 6, on Windows 7 (specs below), but not Ubuntu 10.04.

When I click and drag a tab out of a window (either the main window or a floating window), a new floating window border is drawn with the tab's pane in it, but no tab, and the UI locks up, and one of my CPU cores goes to 100%. By "UI locks up" I mean the entire Windows UI is unresponsive: I can move the mouse pointer around, and I see the cursor blinking in the VS window, but the UI won't respond to mouse clicks or key presses, except for Ctrl-Alt-Del, at which point everything unfreezes and I get the blue screen with the Lock, Switch User, Log-off ... options. At this point I can click on the cancel button and the UI is back to normal, with a new floating VS window containing the tab that I had dragged, now with the tab drawn at the top.

BTW, as implied below for screen size, I have two monitors. The UI freezes on both of them.

Do you see this hang up when you float the window using the document tab context menu's "Float" or "Float All" command? Or is it only occurring when you create the floating group with drag/drop? Do you have any sort of special mouse driver software or similar "non-stock" desktop utilities running?

[mako]

It does not happen when I use the "Float" command on the tab's context menu.
I have a Wacom Bamboo tablet and its attendant driver installed (version 5.2.5-5a on the Wacom driver download page).
I also have a Logitech VX Nano cordless mouse and SetPoint software installed. The SetPoint software says the Control Center Software version is 6.52.74, and the driver version is 5.52.29.

I tried unplugging the tablet and using a mouse instead and got the same freezing behavior. I'm reluctant to try uninstalling the tablet driver, as it took me a while to get it set up the way I like.

I think the freeze is related to the repositioning behavior of the new floating window. Since my original post I have been experimenting and a couple of times after I hit Ctrl-Alt-Del and get control back, the floating window is now in the reposition mode, where it follows the pointer and the relative-position graphic shows up when it is over an existing window. I am able to position it and then use it normally when this happens.

I'm seeing same problem in b5 and b6. As soon as I rip out a tab my system freezes (I have split the MDI window vertically and have multiple tabs in each pane).  Ctrl-alt-del either kills SE or when I return the tab i tore out is sometimes still floating and movable or it is docked.  Tab context menu operations do not cause this problem.

I'm using a Logitech Anywhere MX mouse on a Dell m4600 laptop.

Thanks for the info, guys. One quick thing that I'd ask you to test if could. I'm wanting to see if this is a general drag/drop issue, or just affects dragging out of the main MDI.
1. Open more than two documents and float them (via the context menu). You'll now have multiple floating panes with one file per pane.
2. Attempt to drag from on floating pane into another floater.
3. Attempt to drag a floating tab back to the main MDI.

Looks like we'll have to install the SetPoint software to see if that has anything to do with this.

It likely is Setpoint.  With Setpoint active, dragging a floating tab freezes my system, ctrl-alt-del then esc unfreezes and the first tab had closed.  The second floating tab was still floating.  Same freeze if I then drag that tab.

After I exited Setpoint (from system tray) I could drag the tab and doc it to the MDI (prior to exiting setpoint i never saw the doc icon).  I can now also rip tabs and move them to different panes.

[mako]

I created two floating windows in addition to my main window. The freeze occurs regardless of the type of window I'm dragging the tab from, and it occurs as soon as the drag starts and the new floating window is drawn overlapping the old window that the tab was dragged from, not as a result of moving the dragged tab over a different window.

What Logitech MX mouse do you have? Did you change any options in SetPoint. We have installed SetPoint with a Logitech MX 600 mouse and are not seeing a problem. Do you also have any Waacom hardware attached?

[Clark]

This won't repro on my machine but on another machine here with a Logitech MX 600 mouse with SetPoint, I can reproduce the problem. This problem appears to have something to do with the SetPoint driver. Without it, everything works fine.
