There'll be a collective sigh of relief from S10 owners. Canon have release firmware for download which has been seen already on new S10's. The procedure for update is different depending on whether you have a CF card reader or not so read the download page very carefully. Fixes are: IBM Microdrive compatibility, faster (1/30s) shutter speed for flash shots, auto whitebalance automatically for flash shots.
