hi bigfoot, welcome to the forum !
I'm sitting here looking at a standard issue Canon 32 Mb SD, and a Kingston 8 Gb SDHC, and i can't see any
Could you be more specific, i.e which types of cards work / do not work ?
edit: also, some advice: the above applies in a way to everything you post on the forum:
the more specific you are, the faster you solve your problems
