Really? Two instances of 'not' in a sentence that could be resolved without them.

Well ain't that confusin' ?

Welcome back Pete/Peter, (delete as appropriate)

Don't you just hate double negatives ?

Oh yes there are Stefan. Well, they might be metal, rather than cloth, but they are still there and still called curtains as far as I know.

Take your lens off, set 2 second timer (mirror lockup) and look into the camera whilst taking a pic. You'll see the familiar shutter curtains.

Another web site blip then. I found his post dated 18th March 2009 but his photo usually appears as his avatar.

Laziness comes into it somewhere too. Personally, if a poster can't be bothered to start each sentence with a capital letter, or worse, not bother with any punctuation, then I can't be bothered to read it.

Genuine spelling mistakes and typographical errors are common and forgiveable.

Of course, it doesn't help that we have one the most difficult languages in the world to work with. Their, there, they're ? ? ?

I think you'll find that high speed synch refers to shutter speed, and it only works with shutter speeds faster than 1/180th.

When using shutter speeds up to 1/180th the shutter curtains are fully open (the sensor/film is entirely exposed) at the time the flash is discharged. Faster than that, and the trailing curtain starts to move before the leading curtain has reached the end of its travel. This means that the sensor/film is never fully visible therefore the flash has to fire a number of pulses to expose the entire sensor/film area.

I've never used HS Synch personally and if my perception of its operation is incorrect, Matt'll put it straight.

I think your camera/flash is operating correctly.

The AF focus adjustment on K10D is very different to that of the K20D. The K20D has a 20 lens memory, the K10D has either one (same adjustment applied to all lenses) or four lens memory, depending on which forums you read and believe.

For low light and without additional lighting you need either a faster lens or higher ISO, or both.

K or A50/1.2 (manual focus), FA50/1.4, DA*16-50/2.8, DA*50-135/2.8 are perhaps your best options.
