The problem sounds very familiar. Thjis client had issues with it on a WIN 2008 server (I was RDP'ing via). It was also 64 OS. They claimed there was a fix out which really didn't fix it. Then they started in saying that it was a MAS issue. Then MAS dumped it back into Abra's lap. Ultimately, we just run the link from an XP. Is Abra working on the issue?
