Since I've upgraded Lansweeper to the 4.1 beta I have some annoying bugs when accessing a Windows XP computer remotely. After some use the window does not refresh anymore (I become completely "blind" accessing the remote computer), but still the mouse can be seen moving on the remote screen. I have this problem with version 3.0.0.21, it was working properly with 3.0.0.10 (although very slow refresh rates). I have to switch back this version.
Compared to my older remote control versions this is much slower, can the speed be improved too?
