Hey Joe! Thank you for the details! I haven't seen this issue myself. Can you specify what version of Chrome you're using? Click on the three little bars in the upper right hand corner (under the red X), then on the drop down, click "About Google Chrome" and you should see a Version number on the next page. The current version I have is 40.0.2214.91 - if your version is a number lower than that, updating Chrome might solve the issue.
I'm having the same problem and I am using the version you've listed.
