I’ve been having this issue every once in a while where the property window ends up being inaccessible and locks up my entire designer as a result. When I hover my mouse over the designer in the task bar the property window shows up front and center, but otherwise disappears once I try to close it out. Since it’s not its own window I can’t just close it from the task bar, and since it takes precedence over the parent Designer window I can’t minimize Designer in order to access it; EVERYTHING is locked up. I end up having to close it out from Task Manager, losing any unsaved work in the process. Is anyone else having this issue and is there anything I can do?
