Flash exception from whiteboard #1646

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Don't have exact steps to reproduce, but clicking on the whiteboard after 
uploading slides gave the following exception

TypeError: Error #1009: Cannot access a property or method of a null object 
reference.
