I noticed that using the iPad to remote into Windows, the mouse cursor will "disappear" when it is moved over a white control on a black screen. For the record, the program running on the Windows machine is Waves LV1. It has some white knobs and switches. When the mouse is moved over a white knob, it is completely out of sight.
Could you please send us some screenshots or even a short video of the issue? You can send the files to support@remoteutilities.com in case you don't want to share them on the forum.
