Memory use and rename object

[Clamarc]

Hi,

I have two questions about Sweet Home 3D:
1 - Is it normal for him to use 1422.4 Mb of computer memory?

2 - The geo_triangle_hori object disappeared from the furniture catalog screen, but it was still on my furniture list with the changed name I made the first time I imported it. I imported the geo_triangle_hori object again but when I go to the option to change objects to leave it with the same name as in the list of furniture, Sweet Home crashes and does not make any changes to the name, I have to end sweet home in the task manager to be able to open it again!

Thank's
Clamarc
