Default HotSync & ActiveSync 4 on the same PC

I'm having problem to sync my devices (Treo 650 & iMate JasJar) to the same PC. Each time I try to sync one of these devices, the given device connects to the first BT serial port service defined in BT manager on the PC (Widcom BT stack) whatever the service it is. To be more specific, if I create virtual BT COM5 as a HotSync service and the COM9 as a ActiveSync, both devices try to connect to HotSync (the first BT COM port available). I have also an iPAQ hx4700 and it works ok. I haven't had any problem to sync with ActiveSync 3.8 as well. Anyone with the same problem?

Also I'm having problem to sync some of reoccuring Outlook appointments to the JasJar devices. The are simply ignored by ActiveSync 4. Anyone?
