Problem with mouse cursor disappearing in webplayer

Hi all I have a problem regarding the mouse pointer is hidden when doing specific things in a web player. We have a web player application which consists of the web player and a shopping cart written in html and java script. We have implemented a print feature and a "send link" feature for users to share their creations.

The problem I have is that on some browsers on some machines, when the user clicks print, the print dialog pops up but the mouse is hidden when above the browser window. This means the user is not able to click the print button from the print dialog. Well actually the user can but it is hard to hit the button when you can't see the mouse cursor. The same happens when we try to send a link to the webpage where we use a simple Application.OpenURL(mailto). The print is more complex but it basically generates a new webpage with a screenshot and the shopping cart in a hidden frame and tries to print it with Application.ExternalCall ( "Printing.Print" );.

The problem exists on different browsers and different machines but does not seem to be consistent. It works fine on a dual core centrino laptop with intel integrated with Vista and chrome but not on a new mac pro running win 7 and chrome. Some instances of IE8 also have the problem. The mouse reappears after clicking the browser window, but since our target group are not very experienced computer users this could be a problem.

This is really bugging me since it seems like the error is beyond my control but it would be nice to have a solution for this problem.

Thanks for your help
