Dunno if that'll help any, but I had corruptions when I changed fallocbitmap settings, so just in case that's the reason....
....go to fblitgui>fallocbitmap and make sure that it's like this:
installed > checked
activated > checked
task logging > disabled
task list options > exclude
anonymous tasks > promote
displayable bitmaps > pass on
promotion memory > mem_fast
BTW, are you sure the version is 3.96? Latest on aminet is 3.79a.
