I'm now in the process of migrating my XP laptop into a new Windows7 laptop. With the same setup and cataloges the Windows7 takes 30 seconds while the XP is doing the startup in 10 seconds.
The new laptop should be faster? It has windows7, a dual core and faster processor and 2GB of memory. Strange...

2010-08-23: In Windows 7. Only when serial communicaton is over the Bluetooth link. Normal startup when using direct comm port.

User subsequently reported that this is the "Bluetooth problem".
