Hi Richard, RD> I assume, from the location of the fault shown in the log, that you're using a RD> 32-bit Workbench (your OS4.0 Workbench, that is). Can you try setting it to Yes RD> 16-bit and then running E-UAE again with your AIAB install. You'll get a Yes RD> slightly different fault (or no fault will occur). Can you let me know what RD> happens? Hmm, the screenmode selector came up again and let me choose a 16Bit wb, it loaded in fine then, both in window and fullscreen, but my OS4 WB now looks crippled when unsing MUI apps :-) IT'S ALL PINK ... AHHH, my eyes, going back to 32Bit now :-P After testing there it crashed again... RD> One more thing: what version of rtg.library are is your AIAB iinstall using? AIAB&AmigaSYS: /libs/picasso96/rtg.library 40.3993 (25.04.2005) I have a 40.3945 (16.11.2005) i think in my OS3.9 install CD, though Ciao Hubert --
