Cursor disappears in Altium Designer 10 in the CAMtastic window

Description

There is a bug in the Windows Guest addition driver that causes Altium's CAMtastic cross-hair cursor to disappear when it is moved into the black workspace of the CAMtastic window. I can make it work properly with the following workarounds.

Here are the details:

  1. If I disable mouse integration everything works fine (the cursor doesn't disappear)
  2. If right click on the desktop and set the Hardware acceleration slider to one step below full in the Troubleshoot tab of the display properties dialog I get the proper cursor operation even with Virtualbox's mouse integration active.

I think this may have something to do with an exclusive-or operation that is not working properly in the driver. I attempted to take a screen-capture of the CAMtastic window with the cursor failing and have had no success. The cursor is invisible in my screen-capture. What is really odd is if I do one of the aforementioned steps to get around the cursor bug, I can now capture the cursor with the KDE screen-capture tool. I have attached an image of the *WORKING* cursor. When it is failing the white part of the cross-hair entering the black workspace is missing (it is black like the background).

Again, this is by no means a showstopper now that I have found these workarounds. I am reporting it as the issue may turn out to be more serious in other situations.
