We have (4) users running WF5 M020 on desktops and (1) engineering laptop running WF4 that's shared among us for travel. We need to have WF4 and WF5 on the laptop so I installed WF5 this morning but something is now wrong. When you try to launch either version, the laptop hangs for close to (5) minutes, then the ProE splash screen appears for ~minute then disappears. After that, nothing else happens. If you try to launch either version again (without rebooting - just click the icon again), it loads instantly and runs fine. This happens when the laptop is connected to the network and when you've borrowed a license.
Our desktops run a small .bat file that loads a common .pro and .win file from our server but the laptop does not - it just runs the standalone pro.exe file.
