Just found this through Google -- the "random" window copies were pretty crazy there for a while for me too. Maybe the default should just be "Switch to desktop"? (I've never used a virtual desktop manager that by default copied Windows)

Certainly seems like that was the problem with Chrome, given the name and values of that option, yes. Hopefully everything revolves around this one problem.

:dex:

Have you tried changing the setting "Behavior of windows on other desktops" (Settings > Plugins and Extras)?

[Just to vent my frustration right away: This is VERY annoying, and it nearly totally ruins my experience with Dexpot, which otherwise is a VERY nicely crafted piece of software.]

As I mentioned [url=http://dexpot.de/forum/viewtopic.php?f=12&t=2339#p27800]in this post in 2010[/url], I experience windows-copying. I still do, and I see others in the forum are also experiencing this. My comments in the linked thread mentions a specific, reproducible case about Chrome: If it is the default browser, and thus is the one opening links from other apps, the Chrome instance will be copied to the current desktop when opening a link, if it is not already on that desktop. Thus: insta-copy.

I still experience copying with Chrome more than other windows. However, I now also see it with Visual Studio 2005. And with Citrix.

One thing that [i]maybe[/i] triggers this: My Lenovo Thinkpad sits in a dock, with a screen attached. If I rip the machine out of the dock, stuff happens (as Windows suddenly have to shuffle the windows onto just the one laptop screen). And I believe this might be one of the situations where I suddenly have copies.

[b]Basically: In my situation, I typically NEVER want copies. Couldn't that be an option to totally eliminate the problem?[/b] I guess Dexpot have a list for each desktop of which windows reside there. Couldn't one make it an option to ENSURE that it was just in one list? And also - WHICH situations can possible trigger the situation where it appears in more-than-one?
