I've used a sparkstoothchart(Usercontrol) with open source (www.opendental.com) in my project
When I use the control on a "Windows Forms Application" it's ok, but if I put the computer at hibernate or sleep mode, when visual studio is open and form that contains the control, is in design mode, the next time I turn it on this error comes up:

Fatal Error
can not activate the gl rendering context
and visual studio is not responding!
What's wrong here? I am doing something wrong?
