I have two applications recently recompiled in VFP7 which were running previously in 6. In both apps I have listboxes with Multiselect set on that were working perfectly under VFP6 that now do not support CTRL-Click item selection. Holding CTRL and clicking on a second item highlights the item only so long as the mouse button is held down. When it's released, the item "de-selects." Shift-click still works as advertised, and dragging will select multiple items, but then a CTRL-click will neither select nor unselect properly. The lists are all RowSourceType zero, populated at run-time with AddItem, and are all contained within a pageframe container. A quick search of Microsoft support reveals no relevant references. Am I missing something obvious?
