LDD Preferences Changed on their own

In Lego Digital Designer 4.3.10 the settings in Edit > Preferences had changed on their own, specifically enable sound and keys for turning were checked but I had those turned off.

I first noticed on startup that the background text Safe Mode was gone and then in the application the cursors had changed. Now there is an annoying hand symbol like # 109 and 116 in this page http://www.rw-designer.com/cursor-set/ldd-extract when placing bricks. Prior to that it was a standard pointer cursor and I never remember seeing these hands when using LDD. (All the others like on this page never showed up before either but I don't find them as distracting as the hand things.)

I want to change the cursor back to a standard pointer when browsing and moving bricks. Would this be an LDD corruption/malware problem or OS problem?
