Thank you for your attempt to help me, but I'm wondering if you read my post carefully enough because I said it is not the "baseball mitt" (I've also seen it described as a "Mickey Mouse glove") grab cursor/link pointer that is giving me problems, i.e. it is NOT this icon that is causing me the trouble:
What my problem is, is that sometimes when I am working in Pages (even when it is a text-only document with no images), the mouse/trackpad pointer arrow, i.e. this:
changes into this:
This as I said, is the "Hand Tool" that I get on the screen when I read a pdf in Adobe Reader. It is a normal Adobe icon one sees all the time when one is using Adobe. See bottom right corner in the pic below.
I know that that's what it is because if I switch my Mac on in the morning to work on it, and I open Pages, and Adobe Reader is NOT open, I have no trouble and the mouse arrow pointer appears as it should. But then if I later open Adobe Reader, and read a pdf for example, when I go back to Pages, sometimes - not always - the mouse arrow will change into the Adobe Hand Tool. Sometimes it repeatedly changes between the arrow and the hand WHEN I ONLY HAVE TEXT ON THE PAGE - it has got nothing to do with hovering over images and shapes. If I want to select something from a drop-down menu, sometimes I will get the hand again (NOT the "Mickey Mouse glove") instead of the pointer arrow. It is an intermittent problem; it comes and goes. Sometimes I can work for hours and
there will be no problem, but then suddenly the problem will recur - in a Pages document with text only, no images.
By the way, the cross-hairs that appear sometimes (very seldom compared to the hand), also instead of the pointer arrow, are also the cross-hairs that I know from Adobe, not the ones that I know from Apple. There is clearly some problem of "interference" from Adobe Reader into my Pages programme - why I am I seeing icons from Adobe Reader (the hand tool and the cross-hairs) in Pages, icons that replace the arrow pointer, and how can I stop this - that's what I want to know! I might add that sometimes when I go into Adobe, this hand icon flickers very rapidly for maybe 20 seconds before it stabilises, which again indicates to me that there is some problem with it. I searched this forum some months ago to see if anyone had a similar problem, and I did find someone with exactly the same problem, but I can't find it now. The advice given to that person was to remove the Adobe Internet plug-ins, but I can't find any in Library>Internet plug-ins, and also to submit a bug feedback report to Apple (I have done that).
I might add that in Safari, the problem also happens. The arrow pointer is replaced by the hand tool - NOT by the link pointer "Mickey Mouse glove". In fact sometimes in Safari the link pointer "Mickey Mouse glove" is replaced by the hand tool.
So I hope I have made the problem clear! I don't think I have misunderstood what is going on.
