X Error of failed request: BadWindow (invalid Window parameter)
 

I run a visual program over ssh called XCrySDen. Some computers I have can run it over ssh and some computers will not. The only difference I notice is that the computers with a Radeon video card works and the ones with Nvidia video cards do not. Here is the error I am getting

X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 3 (X_GetWindowAttributes)
Resource id in failed request: 0xffffffff
Serial number of failed request: 815
Current serial number in output stream: 816

Thanks,
