They fixed this in CS4 Comm. Dist. Yay!!!!!

Since CS3 this window will popup for the primary browser if you use the shortcut method (command + f12), even if you check the box that says “Don’t show me this message again.” Option + f12 work fine for the secondary browser forcing me to swap my primary with the secondary (workflow).

This is perhaps more of an annoyance than a bug, but should be resolved.

Pasting and saving untitled.xxx
I love the idea behind the new pasting images (roundtrip) feature with “save for web” compression options. However, when you paste from the clipboard and create a file name and press save Dreamweaver generates “untitled.xxx” instead of the suggested name.

Uses the same name and writes over
What is nice is that it consistently uses the untitled.xxx name, so a change in the file name using Dw site cache will fix the image and the link. But if you do not change the file name and then try to paste a new image, it will write over the original untitled.xxx file.

Why it should be fixed?
So that we do not lose work from overwritten files, and to speed up productivity. If I am writing a tutorial with screenshots, for example,  it takes a lot of time to paste a series of images in by following the above fix method.

Workaround
Appears that you can supply the name in the “URL:” field (instead of the “Save as” field), and it will save the file properly. 

This has been fixed. Yay!!!! It still does not resolve the unix colon at the end of the path, but it does something upon save of site definition. It is kind of odd how it writes the path now. When saved it uses the URL path folder/folder/file.php instead of the unix colons. But, if you browse for the folder it uses the unix colons. Upon selecting the folder, it still does not add the ending colon on the path. But, now when its saved (even without the ending colon) it still points to the testing server properly. I am happy as long as it works.

This has been an obstacle ever since I started using PHP & MySQL around Studio MX. When selecting a folder using the browse feature by clicking on the folder icon, Dreamweaver fails to add the UNIX colon on the end of the path. Works fine in the local category, but not the testing server. If the author is unaware of this, every time he/she goes to preview a file on the testing server, Dreamweaver will end up generating files and folders outside of the intended directory. Relative files may not be published, and things may appear broken when they are not.

If you are ware of this problem you can simply add the colon on the end. If you are new to testing servers this can really add to the confusion, not to mention generate files and folders that were never intended in the first place.

This was one of the first things I tested in the beta release of Dw 10, and it still has not been resolved.
