Hm, doesn't help.
To check on my "slowness"
I modified the Amistart start_stop script to C:wait 2 C:reboot, but anyway having the buttons pressed while the reboot goes off the menu is simply skipped and the usual boot process goes on. Enabling the "One second reboot pause" option also did not help.
Could it be a timing issue that UAE does not initialize the mouse quick enough?
I have tried it several times.
Wasn't this early-startup option modified with one of the last Boingbag updates from Haage&Partner?
I did not install them for Amikit, maybe I should.
I think it's a Linux / Wine system issue as it also does not work here with my own WinUAE setup but on Windows.
Anyway many thanks.
