Eric, Pixeleyz, Marko and Onan,
Thanks for your replies and it seems there is a problem with ML OS 10.8---- I too use CopyPaste Pro, as well as DragThing, aLaunch, TextExpander, SugarSync, InstantShot!, Growl, MenucalendarClock, SlimBattery Monitor, BusyCal, Free Memory, Default Folder and other assistance shareware. But I've used all of these for years and never had this problem.
I have MailTags 3.1.2 - and notice that the sidebar (5 rows of each eMail message) will be blurry and overlap sometimes and that Mailtags is not active. I have to quit and restart MAIL and then all is OK - but that doesn't cure the "suddenly missing cursor" which can and does occur at anytime… Nightmare
I also note that my FINDER windows don't stay set in Mountain Lion - not sure if this is related. I'll do a separate post on this but when I set a Finder window with a picture and put the order of the 30 icons in the order I want, then set for snap-to-grid, when I restart my Mac the picture is gone and the sorting is by name i.e. it has completely resorted my manually sorted icons. I count on having these icons always in the same place so this is another nightmare for me.
Again I shall do a separate post on that issue.
I hope others can report back concerning the disappearing cursor.
