Database Browser Portable doesn't seem to be very portable

I think this app may not be very portable...

I stablished a mysql connection to my xampp on my pendrive, but I got :

Unable to create key 'SOFTWARE\DB Software laboratory\Connection properties'

I think it tries to add a key to windows registry, but I'm not allowed on this computer... so I think this app leaves some traces on he computer you use.

The connection works and that stuff, hope there is no more messages like tha one.
