Slow screen refresh in Windows

hmm.. on my system that code executes on a BMP in about 840 milliseconds.
Try using a JPEG, they are much smaller - that same routine runs in 91
milliseconds when using a JPEG set at quality level 10 in Photoshop (which
is nearly loseless). In fact for on-screen use you can save a JPEG down to
about 5 in Photoshop without any serious degradation in quality.
Also make sure that the native size of the image is used, not some huge
giant image you imported and then scaled down.
