Delphi hangs in Win 3.11 not Win95

Can you help ?

I have developed a project on my home PC which runs fine under Windows
95. However, when i try to open the same project on my PC at work which
is running WFW 3.11 Delphi locks up when it tries to load the default
project.

Any ideas on what's causing this or how i can narrow down the possible
causes ?

Thanks in advance, Neil Pearson
