When running Windows Blinds beta all themes apart from Aero derivatives break the ability to double click on a photograph & it open in Ashampoo Photo Commander viewer, when looking in Task Manager Ashampoo is running but fails to run display anything. The only way to then end the crashed Ashampoo is to terminate it in Windows Task Manager - When running Ashampoo from it's exe it's OK & I can view photographs & manupulate them OK - This problem was also there at times in version 7.4.1 of WB - It's actually stopped me using WB as I use Photo Commander a fair bit - I'm also going to write to Ashampoo support & see if they can find a solution as I like WB, I have no problems with Icon Packager or Fences with Photo Commander - Thanks
