First, welcome to the forum.
Second, two references puzzle me. The first is contained here:
A recent thread in the forum suggested that this could be a plug-in such as Topaz or Nik which is doing the damage
The second is the reference to "LE." There have been many versions of Pr offered over the years, but I do not recall an LE version. Could have just missed it though.
Are you talking about Photoshop, or Premiere? I do not think that NIK has ever done a plug-in for Pr, and only PS. If I am correct, and this is a Photoshop question, you'll want to post to the Photoshop Forum. If it is Premiere, about which you're asking, what plug-ins do you have for it?
Also, other than very slight memory leaks, PrPro CS3 has been reported to be very stable. I'd first look to all other loaded and running Processes in Task Manager>Processes. One, or more, of these is likely your culprit. Now, PS requires far fewer resources, than does PrPro, but it would still be a good idea to trim down all unnecessary running Processes to clean up your system.
Good luck, and let us know about your running Processes and plug-ins, if you do mean PrPro CS3.
Firstly I love your screen name. Trying to sort out my problem with Photoshop has encouraged me to sample a bit myself!
Oh dear, I probably haven't made myself clear. I simply have CS3 not premiere.
The LE version is simply Limited Edition. Photoshop 5 became full version to 6 and so on.
My starting point for loss of computer memory was to visit the task manager and there is ample unused capacity and no significant overloads. It has baffled my computer expert who set up a memory diagnostic test over 50 hours off a boot disk this weekend to see whether there was a fault with the hardware. No fault was found.
If there is anything else you can think of that I might try I would love to hear from you but in the menatime thanks so much for your positive response.
Re-reading your e it seems I should be in the Photoshop forum. Would you mind if I send our exchange here as well, assuming I can do it?
Yes, it seems you should be at Photoshop http://forums.adobe.com/community/photoshop/photoshop_windows
Since Photoshop and Premiere are completely different products, sending anything here really will be no help
I cannot think of any memory (RAM, or Virtual), that I have ever had with PS, going back to ver. 2.5 decades ago. It has always been a wonderful program, and I did not have my first crash until a few months ago. I also have worked on some mega-files in that time, such as triple-truck 1000 ppi images with tons of Layers. The one crash came when Java tried to update, while I had PS open - thought I'd turned every possible auto-update off, but missed Java somehow.
I know that does not help you in the least, but indicates that I've never seen issues, such as you mention.
I would post to the PS forum, as someone might be familiar with your issue and can help you directly, with either an Adobe KB article, or link to a similar issue on the forum.
Good luck, and if you ever do get Premiere, we'll see you on this forum,
I greatly appreciate your time and trouble.
These forums are worthwhile. Without them you feel a bit lonely!
I do agree. They allow me an outlet, while I have a 3 hour Render going on with the workstation. Have not played Spider Solitare much lately...
PS - good luck with your PS memory issue.
