*istD and built-in flash

[David Dixon]

Reading about Don's problems with his *istD and built-in flash has 
prompted me to write.
My *istD developed a similar problem while using the built-in flash - no 
charging, coupled with apparent draining of the batteries and refusal to 
trip the shutter. The flash charging circuitry is obviously damaged and 
it needs a repair.
If this is an unfortunate one-off then so be it, but if this is a common 
fault I'll try to persuade the retailer to fix it for free (of course, 
warranty has expired ...).
So - how many other *istD owners have had this problem?
