Yes.

The virus checker problem occured to me. I asked my client to ask his 
customer if she has set the checker to examine files when they open. If 
so, we'll see what happens if she turns it off temporarily. The delay in 
opening the file would cause the problem; it was the only thing I could 
think of. I'm glad to hear you think it might cause the problem too.

It didn't add the "not 0" part, it's true. If we have to recompile I'll 
do that.

Too true, and by the next iteration of the engine I could have...but I'm 
hoping not to have to rebuild then app. It's been 3 years, development 
is closed, and this is such an isolated incident.

I'm hoping the virus checker is the problem. ;)
