Mike, have we had a regression in the heuler code to reintroduce this
problem? I'm noticing similar behavior.  I thought is was an Internet
connectivity issue on my part as we were having issues but we spent
hours today confirming that the circuits had been repaired and Internet
performance is better than ever here in the test lab but we are still
seeing the delayed screen painting.  The client is 3.99.0.2.  Thanks -
John
