Ok, I'm still rather new to iMacs, but I have a weird problem that may just be that I don't understand how iMacs work. Say I have two finder windows open and I want to click and drag files from one finder window/directory to another finder window/directory. On a PC, I would just left-click the file and drag and drop it to the desired location. But on my iMac (with Magic Mouse) when I click the file and try to drag, the files doesn't drag. I have to click the file a second time to get it to grab the file for dragging. I can never seem to grab the file on the first click. Is this some setting somewhere or am I doing something wrong? It's not a huge deal, but it is somewhat frustrating.
