Thanks for posting those pics, that's a very dramatic comparison. Seeing the two side by side like that makes you wonder what were they thinking?
I don't see two pics in this thread, but if you are referring to the differences in how XP displays the new GUI as vs any of the newer Windows OS's, this was duly noted and reported by several of us during the beta testing. We've been promised a fix in upcoming Update, apparently "they were thinking" that it would take a bit of time to implement such properly.
Likely a case of the way the newer OS's do things internally as to screen display, after all, even the laptops out today feature plenty of graphics enhancements over poor old XP.
There may be a few other reasons besides OS here, for example, the use of different monitor sizes, differing video and graphics hardware and drivers, etc.
PG music enjoys a rather excellent reputation at going after both backwards-compatibility as regards older OS's and equipments, I'm sure that they will come up with ways to make the new GUI work and look great for as many different cases as they can.
Not fair to denigrate this great hardworking Develooment Team with that, "What were they thinking?" line.
IME they are always thinking about ways to better serve the customers.
Ask that question about other outfits that simply turn last year's expensive hardware or software into nonsupported unusables. PG's never done that and I don't think they ever will if it is in their power to do so.
