well, the current version for Windows 8.1+ works almost flawlessly with Windows 10 RS1. The only issue I'm seeing is with the caption text on the title bars. The screenshot I included shows the issue. Basically it doesn't make the caption text's bg properly transparent. This issue shows up on default system themes and custom themes. Also, the modernframe.dll no longer works either. All in all though, I've not noticed any other issues [yet]. I know it hasn't really been updated to RS1 yet, but I just figured I'd give this bit of feedback in case it might be of use to BigMuscle in figuring out what the current issues are so he might know what needs to be fixed.
