Open File dialogs often empty in Mavericks
Since upgrading to Mavericks I've often had problems with the Open File dialog. Often when I select a folder in any Open File dialog in any application, no files show up. This is also true when for example I try and export a photo from iPhoto. The File dialog asking me to select the location to place the photo does not show the contents of existing folders. So once I select the computers hard drive, I can't select a folder or a folder inside a folder to place the photo.
Eventually if I cancel the operation and keep trying, the Open File dialog will work.
This is but one of the many slowdowns I'm experiencing with Mavericks. In general, this has not been a pleasant upgrade, and I have a MacBook pro which is only a year old. At times it seems as slow as a computer from the 1980s.
