Thank you for your feedback! [:)]

Tonight the version 3.4 Beta 26 brings an important bug fix for people using Sweet Home 3D on a computer with multiple screens. This is related to this bug report, this one and this one (in French). Please, if you use more than one monitor, I'll be happy to know if you have still have problems to run the Import furniture wizard on a monitor different from the main one, or if you can reopen a home window saved at location different from the main monitor. Thanks for your help.
