I can definitely confirm that this is an issue. I have video evidence below:
STILL occurring in 1.7.2. I'm beginning to think this is NEVER going to be truly fixed.
Just confirmed that this issue DOES still exist in 1.7.1pre. If it helps, I'm also running Windows 7 Ultimate x64.
This isn't fixed at all. This DEFINITELY needs to be reopened. There is no excuse for leaving this issue unfixed.
UPDATE: Added two additional screenshots.
