CS4 - Layers Display Issue and more

Question

I am running XP64 and have CS4-32 and CS4-64bit installed (using the updated and correct master collection installer)
CS4-32 is basically unusable to me because I cannot see what I am doing as changes are being made to layers. It does it does not display updates to a layer on the screen until I click on the photo. For example, I have a psd file with a background layer and a Gaussian blur layer. A layer mask was used to mask out portions of the blur. IF I simply click the eyeball off on the blur layer, I see no changes to the photo until I click inside the photo. Disabling/enabling the layer mask as the same issue.
If I use the brush tool to make adjustments to the mask, I can no longer see the mask in the layers pallet. The mask is displayed as tiny black and white dots and has no representation of my actual mask. As I brush changes onto the mask, I can see the effects in real time on the photo. But I still cannot see the normal B&W representation of the mask in the layers pallet. If I use the brush tool on the blur layer (not the mask), the photographic thumbnail representation normally displayed in the layer's palette also turns into displaying tiny black and white dots.
b What is causing this issue? Is it a setting that I can change or a bug?
The above issue(s) do NOT happen with CS4-XP64.
Upon startup in CS4-64, I get a GPU disabled message. in CS4-32, I do not. But in CS4-32, my CPU settings are dimmed out and openGL is NOT checked. I have the latest drivers for my video cards installed. In CS3, enable 3D acceleration is checked. IN AE CS3 and AE CS4, it lists that my openGL is 2.1.2 and all features of AE are supported. What open-GL version does PS-CS4 need?

Answer 1

Who was asking for sympathy? I was only asking for help, which a few people were kind enough to provide. I see no reason for people to make posts on other people's threads that do not offer any help. If you think that I am stupid for using an unsupported OS, then just don't post and keep those feelings to yourself. How are posts like this constructive? I even stated in my last post that I knew that I was not going to get any help from Adobe. So why reiterate that? What is the purpose of your and these types of posts? I am as baffled by them as you apparently are about why I am using XP64.
But if you must know why I do not go to another OS, it is because back when I built this computer, XP64 was the only 64 bit OS around. I have this computer in a dual boot with XP PRo 32 bit and XP64. XP64 has, up to this point, been the most stable platform for me to run the adobe suite of products on. I can clearly say this since I have installed (and since deactivated) them on the same hardware under the XP32 boot. But XP64 has, again, been very stable. I have had many iterations of Adobe software on everything from Win 200 to several on XP and on Vista. And without a doubt this XP64 machine has been the most stable for what I do.
The other reason why I continue to use XP64 is because I cannot upgrade to Vista 64 without a totally new computer. The MB drivers have not been developed for Vista.
And lastly, 64 bit allows me to run more programs at once by utilizing more total memory, even with 32 bit applications. I could install the suite on my XP32 version of the same machine but I'd rather continue to use XP64 with CS3 than not having the stability and ability of running more applications simultaneously that I can with XP64.
So yea, my living depends on my software working correctly too and PS CS3 will work just as well today as it worked before I installed CS4. It is just not worth it for me to spend thousands of dollars on a new PC just so that I have say that my computer is run under a supported OS. As we have seen here, a supported OS is not a guarantee that the software does not have bugs in it. This issue will not affect my ability to make a living. It is only a minor inconvenience that will undoubtedly be fixed in time.
