Hi Ralph,
It's good to see you back on the forum!
Sorry that I'm so late replying. I've been down in NC with my Mom, who passed last Thursday (it was all as good as it could have been and don't want to hijack the thread).
I'm not sure how difficult it is to change the size of the anchors, but I suspect it's a bit of a bugger.
One thing you should be able to mess around with though, are the settings for your mouse. Depending on the mouse you have and which version of Windows you are using, you can control things such as speed and accuracy, which may help in your situation. The following web pages have some tips, and how to change those settings on your machine, that you may find helpful.
I hope this helps.
ttfn,
Sherry
