Rick, I've never personally heard of this issue myself. If you go to Dreamweaver->Preferences->Preview in browser, you are saying that "Preview using temporary file" is not checked off? That's the only way I could see DW making those files. Otherwise, only other thing that would come to mind off the top of my head is that there is a permissions issue in the filesystem causing DW to make new fiels because it cannot overwrite the originals. Can you run a Repair Permissions on your system to make sure this is not an issue?
Lastly, can you post the OSX version and DW version for reference.
Yup, preview in secondary browser is turned off. Further testing reveals that if I have a scripting error or I use shortcuts CMND/Option to bring up a direct link to CSS, or if I try and edit an existing recordset from the bindings panel I'm very likely to get a new temp file. It's never opened in an edit window and the temp file never shows up in the site preview unless I browse directly to it.
Weird and annoying for sure. When I get this intranet site completed I'll try and diagnose the problem. No time in the day to do that right now. Deadlines and family commitments don't leave me with the spare hour or so I'll need to figure out what's going on.
OSX 10.7.4 Dreamweaver CS6 Version 12.0 Build 5808
No errors in premissions. Ran a repair anyway. No change.
Also, as per my other post, Dreamweaver is doing this on 3 different systems. A Dell laptop running Windows Ultimate, my iMac and my MacBook Pro.
I have a similar problem with Dreamweaver CS6 editing PHP recordsets. When you edit any elements of the recordset DW CS6 is placing the revised PHP code below the edited and hopefully deleted code. This renders an error. Can't believe that this problem has not lite up this forum.
Googling the problem shows very few references.
