If you’re using the Windows 7 RTM (build 7600), then please be aware that 7stacks v1.2 may not work. Microsoft has changed something between the RC (build 7100) and the RTM that has broken 7stacks. The good news is that the upcoming version, 1.5, does work on the RTM w/ no problems.
Because v1.2 is so broken for RTM users, I will make v1.5 a public beta. I am furiously trying to complete it, and I hope to have a beta ready within a week or two.
I apologize if you’ve had any problems with v1.2. Rest assured that I would not knowingly release software so broken.
Microsoft does have the right to change their product prior to release. But, I just wish they hadn’t changed something so fundamental at the last minute. Oh well.
Thank you for your patience.
