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.
