Hi!
Thanks for your hard work on this project!
I have a bit of a strange setup, as I'm a Mac user, but I love Winamp and never managed to find a comparable player for macOS, so I'm trying to use WACUP now as my main music player.
You may know there is a SW called WINE which is a (rather successful) attempt to translate Windows API calls to native OS calls on linux and mac (and probably other systems too), in other words it is a way to run Windows software on non Windows machines.
After some fiddling WACUP runs smoothly using WINE on macOS. However sometimes, when I have issues obviously I have to try to reproduce the same on a native Windows environment in order to find out if it is an issue due to running WACUP in WINE or is it an issue with WACUP itself.
During one of these checks I've noticed that the Alt Close general purpose plugin does not load on my test Windows 7, but it does load fine in WINE. So I've just decided to flag it with you. I don't have a Windows 10 to see if it may only be an issue with Windows 7, so it may not be a real issue anyway as probably noone is using Win7 any more, but I've just found it interesting that something works better in WINE than on a real Windows. (See two screenshots, one from Win7 and the other from WINE.)
And by the way, I find it rather useful to be able to restart Winamp with a single key+click combo so maybe you could consider adding it as a default to WACUP, especially considering that apparently it was written by You, DrO a mere 17 years ago...
It is almost a legal adult now (at least in some parts of the world.)
