Frozen Application - never had this happen before

[CarolSoprano]

Hi, I have a strange situation that I have never encountered before. I have a Delphi 5 app that is freezing on one of the PC's in a network of 10 users (it works perfectly fine on the other 9 workstations and on the server). Initially the app was giving an access violation in kernel32.dll, but now it's hanging for at least 5 minutes. It eventually opens up without exception but it is deadly slow. Anyway, here is the information:

Can anybody help pinpoint where the problem might be? Thank you very much in advance.
