I'm using Windows Xp Professional SP3 (build 2600), videocard: GeForce 8400GS, Sweethome 3.2 version.
About other applications I haven't similar problems.
Previously I've used this program without issues.
I formatted my pc with the same Windows that I used previously, after installing Windows I can't use normally Sweethome.

But, what I could do to enable write acess?
Thanks for helping......
