So, yeah, I somehow got Construct to work, but not without issues:

Since Windows 7 are going to become the next standard (like XP replaced 98), I guess it would be wise to make Construct conform to Windows 7 a little. But let's wait a bit, it is just a release candidate still and maybe Microsoft will wisen up about some things...
Hopefully.
Anyway, bring 0.99 on!
