I just installed Poser 7 on my Mac running OS 10.5.5. After purchasing content to download from Renderosity the folders download as unzipped folders. I have Stuffit Expander and it doesn't have the option to automatically unzip files-I already checked. Other vendor's content downloads unzipped without a problem. As a result, I haveto manually transfer the files/folders into Poser. I'm not sure I did this correctly or why I should haveto. I emailed the vendor of one of the content material and he's at a loss as well.  Why is this happening? Could someone on a mac please tell me what needs to be done?
