Xojo compiling

For security reasons, I keep my projects in seperate user accounts on my Mac, I noticed recently that every time I move from one to another Xojo recompiles all the plugins. Is there any way to stop this?

Nope
it keeps the prcompiled plugins in a PER USER location

Dave, do you mean that the act of switching causes another need for recompilation even though they have been compiled on a prior visit to that user?
