Anyone else have this weird problem?

I'm developing a program on two computers - One has an ActiveX exe installed that my program references, the other one doesn't. When I work on the that's missing the reference, when I run the program thru the IDE, at some points I'll get a "Can't find project or library" compile error for basic VBA functions like Right() or Space(). Weird...

a few years ago i had that problem for dates in vb 4 (i think)...

Yeah, if I remove the missing reference or prefix the functions with "VBA." it works as expected. Shouldn't the IDE resolve to VBA before it resolves to the missing reference? (Top to bottom in the references box).
