This is almost certainly a case of you having DCOM installed in Crossover
but not Wine. CXSetup will install it automatically in quite a few

I just checked and there are no magic patches in our OLE Automation code
that might make this work.

Probably best to add it but mention it needs native DCOM, after you
confirmed that I'm not talking rubbish.

No, it's just that the Crossover menu code is proprietary and Wines
equivalent doesn't work on modern desktops.

Sounds like a bug we should fix! Can you post a backtrace please?

Ah yes, the hex dump of doom. I've debugged this one before but didn't get
very far.

Basically what is happening here is that the format VB (sometimes) stores
images in hasn't been fully reverse engineered. There are a few gaps in
our knowledge.

IIRC (I looked at this last summer) 0x746c means "Visual Basic resource"
and is a trivial wrapper, the reason the code pukes out is that it seems
to be wrapped twice or something. But I'm not sure why or what this means.
