Thank you for your post.
I believe the issue might be because the window appears to be right up against the wall split and therefore being affected when's it's moved. If this isn't the case, would you be able to please send the model across to email@example.com
Regarding the raked eave issue you're having, there currently isn't an option to create a raked eave for the roof tools so you would need to manually edit the eave to create the rake eave. If you send me the model I will have a look at this also. I can let you know that in the next version there has been a lot of updates to the roof tools that will enable you to do things like this.
