Diving into the code, this one *might* be a tough one to solve. I believe (my guess is) it's happening when trying to parse the icons for the additional applications (and DOSBox, etc.). It's using a low-level Windows API call in order to do this, which is the reason why it's such a challenge.
I did fix the signature of the method, though, so I'm hoping, with luck, that the issue might be resolved. I'm putting out a new beta in a few minutes; Paladin, can you test and see if the issue is fixed? Let me know if you need help downloading the beta.
Thanks,
Jason
