Hi,
It does depend of the lib functionality. Maybe it does provide a property
or a constructor overload where you can set the timeout.
If not you are pretty much without much else to do.
The only other possible solution I can think of is create a thread to do the
Refresh while the main thread sleep for two seconds, then check if the
worker thread is still blocked ( you may use a flag for this) and if it is
do accordingly.
cheers,
