I'm using XP PRO, as I wrote in my first post. And I haven't added any scripts in a very long time, I only use the ones I write myself. My bot has more remotes loaded than I do and there the script editor is opened as fast as it should.

I don't have any unknown processes running cause I keep track of them. But I might try to defrag my drives and see if it helps, if it doesn't, I have no idea what it could be.
