Hi Andras, no that's ok I don't need the file if it is loading for you ok now.

I thought you were talking about the "scene browser" in MoI, but it sounds like you're talking about having other web browers programs open.

So what probably happens with the browsers open is that you end up using enough memory that your regular system memory is completely full and it starts to swap chunks of memory to the hard drive. That's how the "virtual memory" system works, but unfortunately your hard disk is much slower than regular memory access so once you start swapping you can run into a really significant slowdown.

If you want to use other programs while at the same time loading a larger file, you may need to upgrade your machine to have more memory installed on it.
