Hey @lucidBrot ! Thanks for reporting this. I don't use Windows, so unfortunately, I wouldn't be able to help at the moment. If you are able to create a fix for it, please make a PR so everyone can benefit :+1: Cheers !

[conradkleinespel]

@lucidBrot Without further feedback, I'll go ahead and close this issue. If someone else reads this and needs CYGWIN support, feel free to open a PR. Cheers !
