For a few months I have been encountering an issue on multiple different computers and across different versions of R where none of the interactive windows from the utils package and base R are displaying correctly. The functions where this occurs is choose.files, askYesNo, and file.choose (first 2 from the Utils package and 3rd is base).
The reason I believe it is RStudio based is that the only thing that I have found that works temporarily is to go into C:\Users\AppData\Local\ and delete the RStudio folder.
