Thanks James, about the Stack I don't know if you have modified the startup-sequence, with AfA OS you don't need to increase the Stack, this automatically the system thanks to "StackAttack". From my system you can run Dopus4, NetSurf with the standard Stack 4096 without any problem, I have been using "StackAttack" for years and never needed to increase the stack.

Regarding the request for DH0, I usually use SYS, most likely something has escaped me, I do not receive messages because I still have the system partition called DH0 and then is found even if the volume has a different name.
The AmigaLoad icon is not mine I captured it from the program, I also created a version more suitable for icons in DualPNG version, I enclose here:
