Tested your file and it works fine here, despite I have the OpenGL active.

One of the first engines was nowadays forgotten AltaVista Discovery, but it's some eleven years ago... I was even a member of the beta testers group.

I'd also like to point out again that this thread suffers with constant mixing terms of Desktop Search applications and Filename Search applications (like Everything or Locate32). They're mixed even in the poll!

They are hard to compare, because they have different function and different usage. It's like comparing cars to scooters. Both are used to get you from some place to another. The car is definitely more convenient and faster, but if it comes to moving fast somewhere inside building, for example, what would you choose?

While Desktop Search engines usually support searching for filenames, Filename Search engines don't, and if they do, they do it by realtime scanning the files, which might be quite slow, and usually it's limited to text files only.

That's why many people use both. (At the moment I settled on Exalead and Everything). I'd suggest splitting this thread with polls to two separate, but it's too late, I suppose.
