I have the latest version, created a rr.ini from scratch and added resumecheck=true.
I start roadrunner. winamp is running in the background. I create a playlist and it's playing fine. I clear the playlist (including deleting the winamp.m3u) and hibernate with ewf and horm enabled.
RoadRunner and WinAMP are on a non fixed partition.
Next time I resume I create a playlist, which plays fine. (A winamp.m3u is created in the winamp directory on the non-fixed partition.)
I cut power to the system (i.e. don't hibernate again).
The next time I start the system the earlier created hibernaten file is loaded (obviously

).
RoadRunner and WinAMP are running, as they did before hibernating.
The playlist in RoadRunner stays empty though, as it was when the hibernate file has been created. RoadRunner doesn't reload the winamp.m3u in the winamp directory (reloading the winamp.m3u is included in my ONRESUME command)
