Hi, this might be not new to the forum, but for me its not familiar. After the last Update im running 11.2 298 under win10 1903 home. During launch sequenz a dialog pops up and it states (XML prasing error: "not well-formed (invalid token)" at line 2) It does not show all the time, but from time to time. I have searched the program for errors like checking the different rooms to spot something odd, but nothing shows up. The only thing whats strange, is the behavior of the librarie. It seems that the program forget the settings i made like showing the Items list and the extendet details and such. Could it be the reason for the message? If so, how can i fix this permanent? Help as always much appreciate!

I'm going to refer you to this post at Smith Micro which might address your problem. I don't know if it's the absolute solution but at least you have something to ponder while SM still has old Poser posts online. https://forum.smithmicro.com/topic/1557/poser-error-upon-start

Thank you. It seems to be a corrupt file that is written by poser automatically when one changes the UI or settings for the library tab. I'm going to delete them and start with fresh files. It's also the case that I use the old poser 7-8 start environment because it renders faster in SF. But this start scene seems to cause some problems too. Both things are mentioned in the old SM Forum Post you brought to my attention.
