I have had a similar experience with Quicken Deluxe 2014 -- double menu icons at the top, plus account register fonts that are proportionately much larger than fonts in other panes. (Agmanbrad posted on this last June in the General Questions forum.) I'm running Windows 8.1 in Parallels 10.0.2 (27712) on a Macbook Pro with Retina display running Mavericks (10.9.5). I have not had this problem with Quicken Deluxe 2014 on an old PC running Windows XP. All the panes and the menu bar use the same font size. So, following the tech support solution reported by Rev Peter, I have found the change in Windows display settings (“dpi”) to be individually effective, whereas disabling vertical synchronization in Parallels (the virtual machine) was without additional effect, and disabling the Retina display in favor of scaling actually made the text unacceptably blurry, as BryceR also noted. It was an interesting experiment: in Windows, at the recommended screen resolution of 2880x1564, the default size of all items was set to “extra large - 200%”, and produced the menu doubling. By setting this one notch lower, to 150%, most of the menu doubling disappeared and the account register font was tolerably large and the other pane fonts were tolerably small, i.e., still readable. I first went to 100%, as suggested in the Rev Peter post, but everything was much too small to read, although the doubling also completely disappeared. Keep in mind: this is a compromise, as it still does not fix the disproportion between screen fonts in Quicken on Parallels. But it does make it tolerable, enough to enable me to migrate my work with Quicken from the PC to the Mac.
