Disappearing cursor in description

I've been using ZohoCRM for about a year, but I just recently got a new computer and when I began using ZohoCRM on the new computer when I try to write in the description field, the cursor disappears, so I can not backup and delete portions of the text or revise what I've written, without using my mouse.  When I use my mouse it will put the cursor where I want it, but when you type typo's a lot it's frustrating to have to use the mouse to get around a paragraph!  I logged into our office managers computer and had the same problem on hers, and when she's logged in as herself, it does not do that.  So it seems as though it's a setting within zoho, but it didn't do it on my old computer!?!?  It's been driving me crazy and I've been troubleshooting it, trying new settings for my mouse, cursor and more on my computer, but haven't seen those kinds of settings on zoho.  Anyone else had the same problem??
