Hangers in global wiggle

Especially in symmetry- and binder-puzzles I noticed that global wiggling seemed to "hang" quite often. After looking into it more, it became obvious that this had to do with the clash-slider-settings. I very frequently used global wiggle at all CIs set to 1 exactly. And for these settings hangers or rather freezing does occur. With this I mean that even though there are prominent clashes or unidealities in the protein, there will only be a score-increase in the first iteration or so and then the score will stall but the iters will continue counting up.
Further testing showed that this can be avoided when for example the backbone-importance slider is set not directly to 1.00 but 1.03 instead. With this I get for the same protein/setup raising score for each iteration as it should be. This workaround works well for me. But if you don't know this then you can get frustrated like I did. It is also noteworthy that with a second run of global wiggle with all CIs at 1, the score will increase again for 1 iter and then stall again. This whole behavior seems to occur reliably everytime after local wiggle was used before like in my worm-recipe.
This could also have to do with filters because I always have all filters on while wiggling and it runs also well when all filters are disabled. But of course then the glob. wiggle leads in most cases to bad results/BUNs etc.
Even though I have this workaround it would still be good that some programmer could look into this because this may be frustrating for anyone that does not know this like it was for me.
