Unfortunately DisplayFusion doesn't support drag & drop on taskbar icons. All it currently does is forcing the taskbar icon to infinitely flash until your click on it.

The default Windows 7 behavior is that the application will be maximized while dragging, in case it's a grouped taskbar icon it'll open the super-preview and allows maximizing the application/window by dragging on the preview.

Yes, it was enabled by default. I've tested it with WinSCP, Visual Studio 2010 and Microsoft Expression Blend.

Do you want me to test it with a bit more applications ?
Do you need the DF log or a video ?

I've tested a few more applications and it seems most of them are working fine after restarting DisplayFusion. Looks like there was something wrong/messed up.

As you mentioned WinSCP is still not working, Visual Studio and Blend are now working fine

I'll let you know if I find more apps. Thanks so far Keith! <3

Haven't had any further issues with WinSCP or any other tool!
Good job guys!

I seem to be having the same problem, only with ALL apps. I'm running Win 7 x64 pro and DP 4.0.1 beta 2. When dragging on a taskbar button, it just keeps flashing and they never pop up. I have to manually click them in order to maximize them, thereby canceling my drag operation. Very inconvenient.

I had the same problem with the 4.0 release, I tried the latest beta before posting on this forum.

Same problem with beta 3

I've attached a log file. What I did was simply dragged an image on this webpage (I'm using Google Chrome) to the Outlook taskbar button at 11:27:45, which then started to flash. I clicked the button to make it stop flashing at 11:27:50, which opened Outlook.

Note that this is only happening on one particular Windows install. On my other machines, I'm not seeing this problem. All have Windows 7 x64 and similar software installed. Also, on the machine with the problem, I sometimes see taskbar buttons moving to the back of the list, as if they have been deleted and reinserted at the end. Maybe that has something to do with the issue?

That doesn't seem to be it. I have a very clear repro case, but unfortunately it involves having the Xbox 360 SDK installed. When I click on the "Xbox neighbourhood" item in Windows Explorer and not all registered xboxes are turned on, the taskbar button for the corresponding explorer window disappears for a brief moment, and is then recreated at the right of all other existing buttons. I attached a DisplayFusion log of the event. I clicked on it at 15:21:15.

I've installed beta 7, the issue with the disappearing buttons seems to have been fixed!

But I still can't restore a window by dragging over it.

Opened Outlook at 9:45:37
Opened Chrome at 9:45:46
Dropped on Outlook at 9:45:52

I've attached the information you requested.

I do notice a slight lag, but I have to look closely. But they're certainly not as instant as the regular (close/maximize) buttons.

Ok, I just tested it on a machine where I'm not seeing the problem, and I don't notice a lag there so there's deffinitely a difference. Hardware is roughly the same (same videocard (HD 5870), somewhat faster CPU (Core i7 on the machine with the problem vs Core 2 Quad))

Yes that works.

Just wanted to let you know, the latest update (4.1 release) seemed to have fixed the issue for me!
