Blockfish crashes. It used to work mostly OK on the old system though. It's the only one out of this list that I simply cannot use though.
Wusikstation v1 crashes if I try to automate some of the more obscure parameters (that's probably been fixed with the later versions, I'd imagine though). I know, I know...I should upgrade...and I will soon.
NastyShaper crashes the whole PC whenever I use the oversampling option (a real shame - even though it's an old one, I like it).
PSP reverb demo crashed my old Win98 PC - haven't tried it on the new one though.
