[fixed]5.5.4 Reason Rewire panel not showing in 64bit Nuendo

Since upgrading to 5.5.4, I cannot get the Reason Rewire panel to show up in Nuendo 64bit. It works fine in Nuendo 5.5.4, 32bit.
I have a saved project with Reason Rewire active, when I open the project, the channels show up in the mixer, reason rewire works fine, but you can’t get to the rewire panel to select rewire channels.
It won’t open in new projects either.
I wonder if the panel is somehow “off screen” but I can’t seem to loacte it it.
Anyone???

After a second reboot, the panel is now showing. :confused:
