Description Konstantin Savenkov 2006-01-22 14:14:29 UTC
Version:           1.5.1 (using KDE 3.5.0, Debian Package 4:3.5.0-3 (testing/unstable))
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.12-1-686

1. Create a new Entity-Relationship diagram.
2. Create two entities (say A and B), connect them with relation.
3. Assign 1-1 multiplicity to the relation.
4. Move one of the entities (say A) around the screen.

Multiplicity label moves in one direction for different directions of moving the entity which it belongs to. Looks like direction on entity's movement calculated incorrectly, thus circular movement of the entity causes its multiplicity label to run far away from it.
