I have some strange issues with the dbPro IDE, not sure if they are the same issues you're having.
I think my issues come from the fact I have my projects in different locations and not in the projects folder.
I have to launch dbPro IDE from the source dbPro exe and then load my projects through the menu, if it launches from double clicking a project it crashes.
When creating a project in my own location I can't use their directory browser, I have to copy/paste the address in myself.
dbPro IDE crashes everytime I shut it down.
I am using vista, these might not be related to your problems but thought I would mention.
