My Ms. Word used to load very quickly in less than 5 seconds. Though, after installing the RefWorks addon on it a few months ago, it loaded much longer than I expected. It took at least 10 seconds to start the application. I use the latest Ms. Word (2016) with (hopefully) the latest version of RefWorks as well. I tried to ask RefWorks about this issue a few months ago via their Facebook page, and luckily they responded in a few days. They said that they were working on it. But, it seems that they still haven’t figured out this issue perfectly. But it’s ok, most importantly, RefWorks can work on my Ms. Word, despite it’s slow loading time.
