For a while now, I have been suffering from the "Spinning Cursor Pox".
I tried everything. I tried the suggestions of removing the printer and rebooting, disabling add-ons in WORD, disabling practically everything, running every kind of computer cleaner on the market; nothing stopped the spinning cursor in WORD.
I removed Power Designer.
I am now cured of "Spinning Cursor Pox".
Something causes problems with your settings when you download certain products from the web, even if you download the product from the product owner's websites.
happy, happy
