Steps I took that resulted in the problem:
Create a fully assigned part with two or more sub-parts with two or more pins each.
Add an internal connection between any of the pins
Save the part
Drag the part onto the schematic view
Drag a second basic part onto the view (e.g. a resistor).
Attempt to connect another part to one of the pins
What I expected should have happened instead:
The connection should have succeeded

Please also attach any files that help explaining this problem
Here is a simple hack of the SSM2220 part that exhbits the problem:
SSM2220 - Audio Dual Matched PNP Transistor.fzpz (6.2 KB)
Just add it to a project and then try to to move any of the sub-parts or connect any of the pins.
