Hi
Some test results before I clear the cookies and reset IE.
I removed FlashPlayer, rebooted and reinstalled it. Java is not installed. Left the Cookies installed. Checked through the web pages - got any error about 11 pages through the census pages. Went to the page and only got part of the page shown, and other parts appeared as I moved the cursor over them. Tried to move back to the page with the signout option, which me need to jump back to one of the earlier pages and thne jump back again (right clicks on <= button). Got a Norton error and tried to jump back again - got a long wait. Tried again and got an error message that IE had crashed and it then reloaded the page. Jumped back and signed out, and then rebooted.
Tried again while running Task Manager. As I go through the pages, system memory is being used. Currently I am using 3.1GB, and it gets up to about 4.3GB and then gets a problem. It gets the Norton error and then going to the page just gets a black image with no data. Try move forward or back then and I get IE going 100% CPU for a period and having 1.27GB memory. After a timeout in the system, IE reloads the page and the saved memory is released. Then again moving forward works for 12 - 15 pages, with memory growing until it errors again. It either puts up a dialog in the centre of the display or shows it as a warning on the bottom 'ancestry.co.uk is not responding' with a 'recover webpage' button. The dialog then appeared saying that 'Windows was looking for a solution to the problem', the memory is released and the page then reloads. Even if I just view a page, go back to the list of images and open the next one, the memory still grows until I get an error. Also, I normally have several tabs open in Ancestry and I suspect that the problem occurs within the tab, as I can happily use the other tabs while the failed one is recovering.
I have just tried it with Chrome and the memory is not growing as I go through the images.
Checking through the system, the Adobe Flash Player was last updated on 4th December. NIS 2012 was installed in 1st January and the problem has only occured since then, and as far as I can tell since the last set of Windows updates on 11th January. There were some security issue fixes installed then, as well as updates to .NET 3.5 and 4.
I am wondering if are getting a problem between IE, NIS 2012 and Flash Player not releasing memory as it move from one image to another page, and then getting problems with the amount of memory that NIS needs to scan as the number of images grows.
Regards
Chris
