Thank you for reminding us.
I think I know how to fix this one.
I have created a special Skyline-daily that I think fixes this bug that you can install from here:
https://proteome.gs.washington.edu/~nicksh/SpecialSkylines/SciexRetentionTime/
Since this is not an official Skyline-daily, you might have to hunt around for the "Run Anyway" button when Windows tells you that it has not been signed.
I will try to make sure that this fix gets into an official Skyline-daily soon.
