I have currently two problems with Fences:
1) If I download files to the desktop, the files are "hanging" at the upper left corner, under/over my "This PC" Icon. Or a downloaded file moves some Icons away. However, to access the files I have to move my "This PC" Icon and / or to reorganize the Desktop after every download. This is very frustrating.
2) I am using a 2 Monitor + Laptop setup at two locations. In one case the laptop is on the right side, and in the other case it's on the left side. Main Monitor is every time in the middle with same resolution. Sometimes Fences is moving the Desktop Icons to the wrong monitor and it is impossible to move the whole monitor to another, because it breaks the complete Icon-Layout.
