Never used Kies, only ever connected it via PTP or MTP and yes even with those it's doesn't like it much, I find I have to use PTP then swap to MTP and put it down to my computer being a bit stupid and on a prerelease Win8 - though it's pretty much the same as mass storage but without a drive letter, Dropbox automagically sync's all my pics I take and it's rare that I connect it to the computer.
