When I click my mouse the cursor seems to blink 2 or 3 times effectively clicking the screen 2 or 3 times as well. For example if I click to check a check box the check box will tick and then untick straight away after only clicking once. It's almost like it's switching between the Mac and Windows mouse multiple times when I click. I've tried changing the settings for optimising the mouse for games but it makes no difference. Drivers are up to date in Windows. I feel like I'm posting in this forum constantly lately. Not impressed at all. Please can someone help?
