It appears that Microsoft Access may have become corrupted. When I go into design view on a form and click the "Property Sheet" icon, nothing happens. The icon becomes colored in a pale yellow as it normally would but the property sheet is nowhere to be found. I've done a compact / Repair, rebooted numerous times, run the new version of MalwareBytes, and the behavior persists. Also one of my forms that has text boxes making cascading calculations are acting strangely as well. The terminating text box with the result calculation is not displaying the total, even on a requery. The answer displays for a split second and then disappears.
