After OS X reboot - temp file in Trash

Question

Please bear with me if this has been asked before concerning Dreamweaver CS4 (I saw an older post relevant to Dreamweaver CS3, but there was no real resolution).
Situation:
I purchased, downloaded and installed Dreamweaver CS4 onto my Mac Pro (early 2008) desktop running OS X (10.5.8). The installation, registration and loading of Dreamweaver was successful and proceeded as expected. I then rebooted my machine and noticed that the Trash was not empty as it had been prior to reboot. I checked the trash and found a 'Recovered Files' folder containing a file named '_xx41a7.TMP' inside. I placed this file on the Desktop and double-clicked it which resulted in Dreamweaver loading to a blank document workspace.
Note - it is my understanding that OS X moves temp files that were not deleted when a program either crashes or does not quit properly.
Attempted procedures:
In order to troubleshoot my thought that Dreamweaver was the program in question, I performed a clean install of OS X (including updating it to 10.5.8 and installing all updates via Software Update). I then installed just Dreamweaver > launched and then quit Dreamweaver > rebooted. This resulted in the same named file being placed in the Trash about 2 seconds after reaching the Desktop.
I tried a third test where I restored to the most recent Time Machine backup prior to performing the original Dreamweaver install and then installed Dreamweaver along with the additional software options during the install process in case a component was needed for the temp file to be handled correctly. Unfortunately, the result was the same with the '_xx41a7.TMP' file being placed in the Trash after reboot.
System Specs:
Mac Pro desktop (early 2008)
OS X (10.5.8) with all updates
Current installed software:
Photoshop CS4
Illustrator CS4
Bridge CS4
Exchange CS4
Office 2008 (Home and Student)
iLife '09
iWork '09
Aperture 2
Painter X.1
SketchBook Pro
TechTool Deluxe (AppleCare provided)
Stuff It Expander 2009
World Book 2009
I was hoping that there is a setting in preferences or elsewhere that can be set to prevent the constant need to delete this file each time I boot the machine if Dreamweaver has been loaded (this does not happen if Dreamweaver is not loaded prior to reboot).
Note - I am new to Dreamweaver, but old to Photoshop and Illustrator.
Thanks in advance for any help offered.

Answer 1

Randy,
Thanks for the reply and I apologize for not responding sooner.
I did in fact close down all programs before shutdown or reboot (have been for quite a few years now). I also performed a search for said file using the basic searchlight function in OS X, but I have not gone to the trouble of running a terminal command to show all files in finder and I suspect this particular file is normally hidden.
I also looked under 'Preferences/Preview in Browser' and saw that the 'Use temporary files..' was already deselected by default. I tried enabling the option by placing a check mark and then relaunching Dreamweaver and then closing the program, but after reboot the same result with the temp file in Trash. I then tried disabling the option and relaunching Dreamweaver and then closing, but again after reboot the same.
Of note: I have upon three occasions had an empty 'Entourage' folder in the 'Trash/Recovered Files' folder as well. These were times when I had launched Entourage prior to launching Dreamweaver and then closing both before rebooting. Entourage never displayed this behaviour prior to installing Dreamweaver CS4. Not sure what to make of it.
I have yet to hear back from Adobe Support where I placed a case three days ago via the Adobe Support page.
Obviously not a huge deal, but it would seem that this particular piece of software either has a bug or has uncovered a bug in OS X or Office 2008. I tend to lean towards it being Dreamweaver as all my other software never displayed this type of behavior from the first day each was originally installed (all about as old as the original release dates and all patched with the latest updates available).
Does anyone have an idea what function the '_xx41a7.TMP' file serves? It is always the same name, so I am thinking it serves a specific purpose for Dreamweaver.
One other item that may or may not be relevant. I ran a test where I left the temp file in the trash and rebooted and then relaunched Dreamweaver, which resulted in Dreamweaver taking at least 30 seconds to fully load (the application frame loaded in the usual 1 - 2 seconds, but the content of all toolbars, panels and welcome screen took the 30 seconds or more to load). I ran the test a second time and the time improved slightly, but still around 25 seconds total.
After the above testing, I deleted the files (Recovered Files & Recovered Files #1 - both of which had a copy of the same '_xx41a7.TMP' file). This returned the launch time to the usual 5 -7 seconds to load program including welcome screen content.
BTW - I mistakenly listed 'Exchange CS4' in the software list in opening post, which should be 'Extension Manager CS4' (just for accuracy).
