A bit similar to Santosh Y's suggestions...

Often, instabilities in Windows Explorer are attributable to faulty shell extensions and addons. 

Consider using Sysinternals Autoruns or ShellExView. Disable non-Microsoft shell extensions and add-ons, and check the behavior.  If it is gone, re-enable the disabled extensions/add-ons, one at a time, and see if you can identify which may be responsible.

Try a clean boot, or boot into safe mode.  Does the behavior persist?
