I realize that this isn't really a "coding" question per se, but I'm unsure where to direct this question otherwise. If it violates StackOverflow's rules, I'm happy to move it elsewhere.

Recently, when I View(df), the dataframe pops up as a separate window that looks like this:

[![Popup data frame](https://i.stack.imgur.com/XGwRt.jpg)](https://i.stack.imgur.com/XGwRt.jpg)

As opposed to displaying in the Viewer portal in the top panel of RStudio. Does anyone have any idea why this might be? I have a vague suspicion that it may be associated with the data.table package, though if so, I am unsure how to avoid this issue.

Thanks
