I'm finding when I use World Traffic 3 , I'm unable to close the flight setup window .
Cant even drag it.
Have the same issue with the WT3 Radar as well.
The only way to remove the windows is to disable the plug-in.
This doesn't happen if running Xplane outside of Flyinside.
Not sure if its related, but the Flyinside window is always just off my monitor screen to the left, its not a physical monitor setup issue.
Once I managed to expand it to fill my monitor screen and I was able to close the WT3 windows, be dammed if Ive manage to replicate this.
Any help would be appreciated
