Question: I'm having some strange problems with my year-old iMac running OS X 10.7.4.
After clicking on a menu item on the top menu bar, the drop down menu that appears disappears instantly. This also happens when right clicking on the desktop or on an application in the dock. It's as if single clicks are getting counted as double clicks. 

Sometimes, the cursor just disappears. It reappears when moving the mouse, but keeps flickering.

It's not a problem with my Apple wireless mouse. I also tried a wired Logitech mouse and had the same problem; so, it must be a software bug, not a hardware problem.

I started experiencing the issue after doing a software update to OS X 10.7.4, but I'm not sure if this is the cause of the problem.

I have uploaded a video of the problem here: <http://tinypic.com/r/2vxk9af/6>

Answer: 
In addition to iGameRam's answer, you can transfer files by either a [dropbox](http://dropbox.com/ "Dropbox") or [iCloud](http://iCloud.com/ "iCloud") or other cloud solutions. Depends on the file types and applications that you wish to use them with.
If your question is like "can i transfer files from PC to iPad 3 without any software" then its a NO AFAIK. If its just to avoid iTunes then you can used [Disk Aid](http://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CFQQFjAA&url=http://www.digidna.net/products/diskaid&ei=Gr76T-rlD9HQrQfH_K3HBg&usg=AFQjCNFqV8BjHQNC4zjU6_iSVq42HThEKg&sig2=JaqSTNAbDh6BxYuvNKqPQA) or similar softwares. Hope this answers your question.
