I have been monitoring the s3d forum on a daily bases for years now.. 4.10 is a mess and from what I could see, there is nothing good about it. Things that worked logically in 4.01 are now non functional or work the wrong way. They say the fix stuff but there are no patches, or updates.. not sure if they actually fixed any of the bugs.. Reinstall 4.01 and get you print sliced and printed !
