/about/blank Error
Hi,
I'm running OS X Yosemite 10.10.2 on a Macbook Pro.
I've got Adobe Flash Version 20.0.0.228 with NPAPI Plug-in version 20.0.0.235 and PPAPI Plug-in version 20.0.0.228 installed.
I use Google Chrome as my browser, but this error only appears when I am using the Vuze bittorrent client application. It has only started happening in the last week or so. Before that everything was running fine.
This is the error message that appears while Vuze is open:

It will appear for only a second or two before disappearing. After that, if I click on any window in Vuze, all Vuze windows suddenly begin flashing and I am unable to click away to any other application and I have to force quit Vuze.
I have tried adding both /about/blank and cdn-static.liverail.com to my allowed sites in the Adobe Flash Global Security Settings, yet the error continues to occur. Any idea what's going on and/or how I can override Adobe Flash Player's security settings? Any help would be appreciated.
Cheers!
