As I said, I'll think about whether something can be done to solve the problem, but I don't think that this approach will work, even if it were feasible (the Rcmdr doesn't keep track of the packages that are loaded by dialogs and even if it did, if wouldn't know about packages that are loaded as dependencies of these). For example, the Rcmdr previously detached the rgl package before closing the Commander window and this created problems for some plug-in packages.

Best,
