I run WIHU at T-12 and at this stage of setup on my Turion64X2 -fully_unsupported_by_windows-, visual themes make the installation lag. On VMWare, the problem is less apparent.
The worst case I've seen so far is when installing Dev-Cpp : it shows a list of all processed files and there are tons of then. But as soon as I move its window out of the screen, the installation goes 100 times faster (really!).
I've tracked it down to a windows visual tweak called "smooth-scroll lists". It is a very CPU-intensive tweak at T-12 and takes something like 0.3s for each new line added to the list. Imagine how long it takes for 50 elements!
Plus it renders really ugly and completely unreadable.
I don't know how to disable this tweak at this stage of setup (I know in fact but it's just an overkill).
My request is simple could WIHU refuse to be themed or be subject to such a tweak ?
I'm asking because I believe it can be very fast to implement and I'd do it myself if I had VisualStudio (ATL).
Thanks a lot.
