The puzzle comments say: "Players may also delete and redistribute residues on either side of the prescribed binding loop."

This is not possible for me. I could add residues, but not delete any residues, not even after I had added some.

Both rebuild and remix recipes seem to hang on the first rebuild or remix, never advancing. Cancel does not work, the message "cancelling" appears in the upper left, but it hangs there indefinitely.

This problem can be produced a manual remix. After selecting segments and starting remix, the first remix result is displayed, but remix hangs when you try to advance to the next result. Clicking the "X" to close remix has no effect. The only option is to close the client window, which seems to work normally.

In log.txt, a manual remix shows these results:

***** STARTING THREAD ActionBuild

done.

The "illegal operation" message appears at the point where you manually close the client.

Attempting a manual rebuild crashed the client with the following in log.txt

***** STARTING THREAD ActionRebuild

Running TvdL EDRW didn't cause a crash, but it did hang on the first rebuild.

Segmentation Fault 11... will post feedback. Crashed 3x... so this is still broken on my Mac

when using some of the shake-wiggle-mutate functions... cancel or stop doesn't work (intermittent), ESC will stop or cancel.

can't see the player list too

Shake takes forever, because it also shakes the big part.

I ran Local Quake on it for a while but the progress was way too slow (probably because of shake). I switched to Enhanced DRW on small subsets of the protein but encountered a crashes almost immediately. I don't currently have the inclination, patience or time to coddle this type of puzzle along.

can't get it to stay up long enough to do much on it

I can not run and rebuild or reset scripts; I can not reset manually; I can rebuild manually though if I convert it to loop I can not manually rebuild. Also Idealize scripts seem to do nothing; though again I can manually Idealize.

On MAC.
