Why is Premiere Pro CS5 slower on my system than Premiere Pro CS 4?

Question

I just upgraded from Production Premium CS4 to Production Premium CS5.  Have Windows 7, 64 bit OS, 9 GB ram,
Intel I-7 quad 2.67 processors (over clocked to 2.90 ghz) with hyperthreading.  I have nothing of any real substance
operating on my system besides Adobe.  I have just loaded in a ton of DVC PRO HD 60 footage and am editing a 30 minute
program.  Once I am in Adobe Premiere Pro CS 5, it works fairly well, everything works well real time.  However, the moment
I click outside of Premiere Pro like to my desktop, then try to click back into Premier Pro, my screen goes white, Premiere Pro says
"not responding" in the title bar and everything freezes for about a solid minute.  CS 4 did not do this at all.  Anyone know what is happening?

Thank you Harm for the info so far.   I appreciate it.  Seeing that this is an issue, let me give you a little more data than I might normally do in the hopes of helping to resolve this issue and possibly, you will be able to distill from this something of use for all of us.
I tried out what you said to do, clicking in the timeline first or even while the blue wheel is in motion, but it makes very little difference.  Let me give you a little more info.  As an attempt to have resolved this which I have not, I am essentially working offline and the problem still persists.  I have internet connection disabled, I have all anti-virus and firewalls turned off, I have gone through the task manager and have ended every single process not essential to running Premiere Pro CS5.
All it takes is for me to click on the desktop with nothing open and then click back to the Premiere Pro CS5 window whether it be in the timeline or anywhere and I get the blue circle going.  When I do what you say, even while the blue wheel is going, and I try to click on the timeline, the premiere pro window goes white with the blue wheel still going and locks up for at least a minute.
Some other outpoints that may be related to the same issue:
Additionally, when using the media browser and I double click on the P2 media thumbnails to bring the media to the source window, I get a long delay
to load the footage.  Usually about 10-15 seconds for EACH piece just to view it.  Needless to say, this makes editing essentially impossible. I have also tried settings on the memory preferences section changing between "performance" and "memory" not really knowing if that would have anything to do with it, but it didn't.
Another mysterious thing is that my editing tools window never shows up even, even when I reset the editing workspace (window-workspace-reset current workspace (with "editing" bulleted).  I have to manually open up the window and then drag and drop it back to its normal place each time.
Needless to say this is making the experience terrible.
I checked my loaded and running programs to further resolve this to make sure I did not have some unknown system drain, and happened to see I still had the old Production Premium CS 3 installed but not running, so I uninstalled that and it made no difference.  It hadn't been running anyway.
What is frustrating, Harm, is that my Premiere Pro CS4 was running great.  When I started working with P2 media on CS 4 on the same system, I had noticed a similar lag in loading P2 media which I thought was odd, but I NEVER had the delay and blue wheel and white screen clicking from one application to another.  The only time on CS4 I even experience a slow was when I had PPro4, AE4, AME4 and Encore 4 all opened at the same time!
Funny thing though, when I have Premiere Pro CS5 and AE CS 5 opened, AE runs fine, but Premiere seems to be hog and is just slow.  I never have a problem going in and out of the other Production Premium applications.
I am using an Asus computer, with Intel Core i7 processor 920 @ 2.67ghz.  I have standard overclocking software, and when I overclocked my processor to run as an i7-940-2.93 ghz, that lag on the loading the P2 media into the source window went away on CS4.
However, since being on CS5 it now does the same thing.
It is so bad that I thought I okay I will go back to CS 4.  However, now when I try to use CS 4, it is doing the same thing, yet this did not do that before installation of CS5!
Let me give you just one more bit of data in the hopes that it may help in resolving this.  The way I installed Production Premium CS 5 was first via
the trial software.  While that was downloading, I purchased the software and I installed the serial number at the time of installation.  The reason I mention this is that before I purchased it, I was interested in seeing if CS5 would handle a codec problem I was experiencing going from premiere pro to encore DVD ( this will be the subject of another thread) and I was assured by the salesman it would (it didn't) and that the trial software is fully functional!
Well, that is untrue, and the salesmen and the sales supervisors (spoke to them all) are very seriously misinformed.  The Trial version is NOT fully functional, however, you do not find out about it until you actually get the download page and then it clearly says in small print that encore and various HD codecs are not operational as well as some AE aspects on the trial version.
The reason I tell you this is that I don't know if installing via the trial software version makes any difference in how it sets up.
The significance of this is that I was told that Premiere Pro, After Effects and Encore build upon CS4 and you cannot uninstall CS 4 before loading the upgrade to CS5 nor should you uninstall it afterwards.
So this now possibly explains why the previous CS 4 I have on the system is also now responding just like CS5.  (I don't know if it makes any difference, but CS5 installed Premiere Pro, After Effects and Encore in the C:\Window\Programs folder yet all other components are installed in the C:\Windows\Programs(86) folder.  (My dynamic links work fine (so far) between Premiere and AE and Encore)
Okay, Harm, sorry I wrote so much but possibly this will help, and I hope there is something I can do immediately to resolve these serious delay (lag) issues.
PS:  I have three internal hard drives.  CS5 is installed on the C drive same as my OS and all my footage and premiere pro pjts are saved onto a different drive. Everything is 7200 rpm, 1TB,  Sata 3Gb/s..  Except the internal drive where the PrPro Pjts and footage are stored is 2TB , 7200 RPM and 6Gb/s.
