@mapleleaf – Besides the error I described, the use of 2 MONITORS is definitely also part of the problem if you updated to version 9.1.4.0…
This is a very long thread BUT basically as you get further down, it was found that most people were using 2 monitors–when they used just their laptop, they had no problems,
I still have errors that happen that were reported originally in RM 8—the problems is that as they try to fix an error, the techs have to make sure the fix does NOT CAUSE more problems and sometimes figuring out what is the cause of the problem is like looking for a needle in a haystack…
