And the only thing you installed in the Sandbox environment was Start11, yes? (important to know).
I don't show that you have Start11 under your account - are you using the trial? Do you have the license under a different account?
If you are comfortable with working on your Windows Registry, go here:
Zip it, with your userName in the name and PM it to TPScroggins, please:
Start11 and Firefox were the only two things installed in the sandbox environment. Got the same result, with new windows opening unexpectedly on left-click, and taskbar previews not responding to left-click at all (previews only respond to long-hover with taskbar enhancements enabled).
I also have an additional issue where the Start11 taskbar opens on the monitor where the mouse cursor is currently located, instead of always opening on the primary monitor. This also doesn't match the default Windows start menu behavior, and there doesn't seem to be a way to configure it otherwise.
I'm currently using the trial on multiple computers. I'd like to see some of these bugs squashed before I make a purchase.
I'll get that regkey exported, zipped, and sent off for analysis. Thanks!
