Good day all.

any chance you can do a control-s and post that file here?


Thanks for quick response. yes I have posted the files at different flight alt below.

I changed extensions to .txt as .grid would not be accepted. I hope it works.

So latest version available for download? I see the last one was loaded up on the 9th Dec.


latest beta will have it.

Thanks you very much. I will give it another try.

Oops, I never installed beta version before, it seems there is no installer. Is this portable version I suppose?


goto help > update beta

I’ve been seeing this issue as well. I am on version 1.3.56 build 1.3.6672.30243, which I just updated this morning. I just did the beta update which is build 1.3.6694.6400 and the issue is there as well. I’ll upload the .grid file.

Perfect - that was exactly the issue. Thanks for the quick reply!
