In a recent change, the dialog that allows users to select variables for inclusion in a QScript when it runs (e.g., "Insert a table > Report > Crosstabs") makes it difficult to select "sections" of variables or lots of variables at the same time. Consider a document with thousands of variables, and you want to create crosstabs of a subset - you would have to select each of them individually (or select all, and then deselect those you don't want), whereas before you could click one, hold down shift, and then select the last one in a section of variables, and/or hold down ctrl to add more. The dialog should allow both forms of selection, i.e., check-boxes and multi-select using shift/ctrl.
