1.) In the list of screensavers to be started after JkDefrag finished are not listed all installed screensavers.
Cal you tell me which screensavers and where I can download them?According to Microsoft all screen savers must be called "%SystemRoot"/system32/*.scr". What are the filenames of the screensavers that are not listed by JkDefrag?
I don't know whether it is the official feature, but windows list in its dropdown list also files matching "%SystemRoot"/*.scr". Anyway, if you support only "%SystemRoot"/system32/*.scr", it is good enough for me. I just needed to know. when I copied all *.scr from %SystemRoot to %SystemRoot/system32, all screensavers are listed.
2.) Chosen screensaver is not started after JkDefrag.
JkDefrag starts screensavers by executing the following commandline (you can simulate it by entering it in the "run" box in the start menu), in this example the Windows "beziers" screensaver. See
http://support.microsoft.com/kb/182383 for more information about this commandline. I am guessing that the screensavers you are having problems with do not follow this standard? If you can tell me how they need to be started then maybe I can work it into JkDefrag.
cmd /c c:\winnt\system32\ssbezier.scr /s
cmd /c c:\winnt\system32\ssbezier.scr /s or in my case cmd /c c:\windows\system32\ssbezier.scr /s works fine, but my screensaver does not start after JkDefrag (any screensaver). I don't have any idea about the reason.
3.) It would be nice to have possibility to set also zero hours to start again

Do you mean that the screensaver should loop? Or always start defragging whenever the screensaver kicks in, as it was with the previous version?
I meant the second one, but this is really not important.
