IE 7 100% CPU While In Lorebook

Meant e8400 it is intel.

I meant to check it out on my Vista PC at home last night, but I forgot. I'll try to remember to do it tonight.

When I get the CPU to hit 100%, IE7 doesn't lock up entirely like I think it is with Avaton. The page just runs a little slower than normal, then within 1 second of keeping the mouse still it returns to a normalish level. Also, I sort of have to "try" to keep the CPU at 100%. It will normally be around 80ish with spikes up to 100%.

This issue has definitely taken charge of the greater part of my curiosity

Thanks DYMongoose,

On my machines it pegs the CPU so completely that I can't even close IE without killing the process from the Task Manager. That is, unless I wait several seconds without moving the mouse until it lets go of the CPU.

I need to reformat my wife's computer this weekend (holy moly it's loaded with junk!). I'll update XP on it with everything except IE7 and see if the Lorebook works with IE6 on XP SP3.

Haha, sounds like my parents' PC. I can't count how many times I've reformatted that machine...

I'll be interested in hearing what you discover with IE6. If it works better than IE7 I might cry a little.

I tried this on my work computer, a 2.4GHz P4 w/ XP SP3 and IE7. For a few seconds I managed to get it to peak at 100% when mousing over the menu, but most often it wouldn't go past 50%. It's hyperthreaded, so it has 2 CPU windows like a dual-core system. It always dropped back to 1-2% right away after stopping the mouse though.

OK, so from my Vista SP1 PC (Core II Quad, 3 GB RAM) I tried hard and can't get the CPU over 30%

It looks like it's an XP thing, possibly SP3.

No problems on my wife's computer after the reformat. As soon as I installed IE7 though the problem came back.

After digging at the issue a bit more I noticed that the slowdown occurs when hovering over the items on the left but after the pop-up menu appears everything returns to normal.

For example:
If click the Lorebook link from the lotro.turbine.com homepage and don't move the mouse the page loads slowly but the CPU sits at around 5 to 15%. As soon as I move the mouse the CPU hits 100% on a single core (50% in the process window) and stays there. When I stop the mouse over a link on the left like "Items" the CPU stays at 100% for about 10 seconds then the pop-up appears and the CPU drops to normal. If I move the mouse around inside the pop-up there are no problems at all and the sub-pop-ups appear as one would expect and the CPU never goes above 25%. As soon as the mouse leaves the pop-up menu the CPU hits 100% again.

I did some google searches about javascript being slow on IE7 and such and it seems many people are having issues with it but nobody has a solution Oddly however, many people with IE7 are having no problems at all. Strange...
