Why, oh why, did Hikvision obviously not test iVMS-4200 using a bluetooth Magic Mouse? The software jumps around like a demented chicken whenever and wherever the mouse scrolls. It's near impossible to hit the required tab - and 100% impossible to use the eMap function as the map scales down to uselessness every time the mouse cursor moves. Surely there are some other sufferers out there? This is a popular and expensive Apple mouse which works just fine in every other software application...
