While using the healing brush in Lightroom 5 my mouse began to behave erratically after a few hours of use. Initially I thought the batteries in my mouse were dying but when I turned of the healing brush the mouse worked normally. In fact, with the healing brush turned on I can mouse over the tool menus with out any difficulty but as soon as I move over the picture that I am editing the mouse begins to behave erratically. It also does this with the red eye removing tool. I've tried switching from my wireless mouse configuration to a wired mouse configuration and I checked all my drivers, which were up to date. I've also tried closing and reloading the software. I have read and spoken to people online who have experienced the same problem but there solutions have as of yet not corrected my problem. Thank you.
