Looks like this is new. 4.3i doesn't have the problem.
Interestingly though, in both 4.3 and 4.5 the list of classes in QBE
includes a bunch of classes that aren't in the model and don't look like
system classes, e.g. in GrainGenes' case Clone, Comment, Doc,
Homology_group, Include, Paper. In 4.5 these "extras" don't appear in the
scrollable Selector window obtained by clicking the triangle in the Main
window or the Query Builder window, only the one obtained from the QBE
