Infinite loop in conflist resolution algorithm

[Marc-Winner]

It seems that sometimes algorithm is stuck in simple kind of infinite loop.
Simple check whether the algorithm recreates previous state may be the remedy.

Steps to reproduce the bug:

1. Use lingtrain/studio:v8.4-labse
2. Load the alignment database (attached below)
3. In alignment settings choose Window = 20, Align and resolve through the subscript: "For the left text"
4. In Customize Press "Apply"
5. Press Align Custom. After calculation there should be 72 conflicts
6. Then Press Resolve All. You get an infinite loop (see the attached log below): after each attempt there is exactly 14 conflicts.

Hello!

I've loaded the alignment and seems that there is no conflicts.
Anyway, can you provide the subscript file you used? Because in the last version (v. 8.4) there is no ability to choose "For the left text" option in case of loading the .lt file.
