Thanks for the reply...yes, there are so many settings for this virtual desktop tool that some will get missed. Your suggestion does appear to give me 2 working choices, either of which is fine.
So thank you, and please try to cut those of us that are overwhelmed by the shear amount of settings available a little slack, too. I've never used a single tool before that had this many settings, most of which I've never needed to touch. For example, if I have an application set to stay on a particular desktop, how does it make sense to copy that application to my current desktop, I already asked to keep it on the assigned desktop? That gives me a "copy" of that application on the wrong desktop that if I then dismiss, gets rid of the original (hence the term "copy", I do understand that, that it is only one actual application, I mentioned that in my original question). The only way that I can see to get rid of that copy without killing the application is by moving the copy back to the desktop where I asked it to be assigned. That is not intuitive to me, and still seems to be a bug, even if only a usability one.
So that's why I thought this was a bug, since it didn't work as I expected it to, I didn't expect it to make a copy on my current desktop after I'd already specified that the application be assigned to another desktop, and it didn't occur to me that this could be the result of conflicting settings, since it just didn't make sense. Especially since this only happened with the Chrome browswer, while Internet Explorer behaved the way that I expected.
And every time I find something that doesn't make sense in a tool that I'm using, I have to question whether I really want to use that tool, since I can't predict its behavior. Again, assigning an application to a desktop means (to me) that if I bring it up on another desktop that it will come up on the desktop that it is assigned to, not make a phantom copy of it on my current desktop that I have to return to the desktop where its supposed to be in the first place so as to not kill the application.
So there you have it, my reasoning makes sense to me, probably not to anyone else, though *smile*.
And again, thanks, in the unlikely event that you've read this far *smile*.
