In the 3D view still having the problem of the Preferences window into hiding, unable to access it.
This just happened to me again too for the first time in a long time. I'd just turned on the network and was looking at some aircraft over Switzerland, and I'd just successfully bumped up the Network detail to "maximum". A minute later went to check the setting and the preferences pane was popping up under the main ANRB app.
Added to bug list above.
Airnav - I also noticed this version has the beta_log file enabled again, so I've sent it to you, along with the ANRB.elf file in case there is anything to help identify the problem.
