Mouse Pointer is changing sizes

Setting up a new computer and running into an issue i have not seen before...

when the mouse pointer is pointing at menu items, color palettes, dockers, etc. the mouse pointer size is normal.

however, when i put the mouse pointer in the document area it triples in size, making it almost unusable.

admittedly, i am using a Wacom Cintiq which often introduces it's own issues, but i have never seen this before.

i thought it might have been a corrupted workspace, but when i change it to the default it still occurs.

Any suggestions?
