Finder freezes after dragging a file to the desktop

Question

I am finding the if I try to drag a file to the desktop, it seems to move the icon there, but then freezes up... you can't do anything with finder at all..? I go up to "Force Quit" and select to "Relaunch" Finder, and it resumes normal operation... My work around is to copy and paste things onto the desktop, them trash the original file... a poor solution, but I'm getting by.. any ideas??  Dave

I appreciate the update DJ.
Next I would verify and repair the startup disk using the Disk Utility. This resource should help you do that, named:
Repair a disk - Disk Utility Help
Print this help page so you can refer to it later. (You don’t have access to Disk Utility Help when you restart your computer in the next step.)
In the Disk Utility Help window, click the Share button , then choose Print.
Choose Apple menu > Restart. Once your Mac restarts and you hear the startup chime, hold down the Command (⌘) and R keys.
When the Apple logo appears, you can release the keys.
Click Disk Utility, then click Continue.
In the sidebar, select the disk or partition you want to repair.
Click First Aid.
If Disk Utility tells you the disk is about to fail, back up your data and replace the disk. You can’t repair it.
Click Repair Disk.
If Disk Utility reports that the disk appears to be OK or has been repaired, you’re done. Otherwise, you may need to do one of the following.
If Disk Utility reports “overlapped extent allocation” errors, two or more files occupy the same space on your disk, and at least one of them is likely to be corrupted. You need to check each file in the list of affected files. Most of the files in the list have aliases in a DamagedFiles folder at the top level of your disk.
If you can replace a file or re-create it, delete it.
If it contains information you need, open it and examine its data to make sure it hasn’t been corrupted.
If Disk Utility can’t repair your disk or it reports “The underlying task reported failure,” try to repair the disk or partition again. If that doesn’t work, back up as much of your data as possible, reformat the disk, reinstall OS X, then restore your backed-up data.
If the issue is not resolved, I would next re-install Yosemite. This will not compromise your data:
