v2016, Standard Desktop for 100c. Occasionally, I get stuck to where I can't change modules. Currently, I'm in Library Master, having just added a Report via Report Manager and trying to go to Sales Order. I click on any module on the left side and it doesn't take me to the module. If first time into the module, it prompts me for the date, but doesn't take me there. I tried going through Change Current Module at the top menu and also the bottom Status Bar and I get this blank Modules Window. Only way out is to close Sage and open back up. It's happened before, but I can't remember if only on this customer or other customers too. Anyone seen this?
