you mean, that sys_fopen() is crashing and never returning (rather than
using the FILE returned by it)?cd
can you open other files with Pd?
e.g. can you *save* a Pd file?

Yes, when my midifile dll calls sys_fopen in the running instance of Pd, Pd disappears from the screen. I was getting a crash report dialog, but not any more. The Pd program runs fine, I can open and save patches. Also the version of [midifile] from deken works fine, but I don't know how that was built.
