This issue started after installing the latest version.
At first the issue was that if I close construct with the tilemap window closed (only when it is not docked), when I open construct again and select it from the view panel, it doesn't show up.
If I leave it selected, exit and return, it comes back again.
I tried resetting all dialogs from the Preferences screen to see if it'll fix it.
But this caused a another issue with the z order window, by default it is off, but now even if I turn it on, exit and return, I still don't see it.
I tried resetting a couple of times, and I still can't manage to get the z order window to show up.
Note: If I run an older version of construct, I can see it, then when I return to the new version it shows up too.
