Forget what I said about script, it has nothing to do with TinyLauncherSE.
Edit your startup-sequence like this :
at the first line, insert:
Assign TLGECS: DH0:TLGECS
save the modifications.
reboot your Amiga. done!
You must have the application "whdload" in c:
You must have some "kickstarts" in DH0:Devs/kickstarts (At least the Kickstart 1.3 and Kickstart 1.2)
If it's ok, then you are ready to go !
As I have started to work on the Mods before you report the bug, it's for the next release (this weekend probably) with the Mods
