Memory leak in the design tool?

Hi — I have been using Upverter quite a bit recently and I have found that after I leave the tool open for a while it becomes very slow, forcing me to refresh the page. Occasionally it will even eat up so much memory that OS X informs me that I am out of application memory and I need to close Chrome. This has only ever happened using this tool. Perhaps there is a JS memory leak somewhere?

I am using Chrome 54.0.2840.98 on OS X 10.11.6 on a Macbook with 16GB RAM.

Google chrome cant manage its memory, try Safari, or Firefox. V8 (The javascript engine behind Chrome, and NodeJS/Etc), is very bad at Garbage Collection, (The act of clearing un-used memory), i’m using Safari, on a MBA from 2011, and it works fine. Leave chrome, it’s terrible.
