Hello,
Getting started in PropView.
PropView is the only program installed other than the mandatory Launcher.
When I start to enter even the first digit of the Latitude, the font is "Red".
Also, my minus-sign is not accepted for the Longitude.
My keyboard has two keys for the minus-sign; neither of them is accepted.
So, it is no wonder that the Latitude/Longitude values (40.1778 & -77.1972) are not accepted.

Entering N40.1778 and W77.1972 does not work; still get the "Red".
If it is significant, my grid-square is FN10je.

I've yet to find what I've missed.
TIA for any assistance.

+ The DXLab Launcher is not mandatory. It's a much more convenient way to install and upgrade DXLab applications than doing so manually.

+ As described in

https://www.dxlabsuite.com/propview/Help/Operation.htm#Transmitter%20panel

+ latitudes and longitudes should be specified in standard geographic format, e.g. 42 70' 30" W.

+ Striking the Enter key in the latitude or longitude textbox causes PropView to review the validity of each; invalid latitudes and longitudes are colored in red.

Entering N40.1778 and W77.1972 does not work; still get the "Red".

+ That's not "standard geographic format".

+ You may find it more convenient to direct the Launcher to download and install DXView, as you will then be able to designate the target of a propagation forecast by entering a DXCC prefix or by clicking on a location on its world map.

Well, it worked finally but only after hitting the enter key.
Sequence of events:
1. Entered Latitude in DMS (42 70' 30" W) but everything was red, which remained as momentary "source of confusion" for me.
2. Entered Longitude in DMS (42 70' 30" W); that was black.
3. Hit the enter key and that action changed the red to black; also put in my Grid-Square correctly as FN10je.
So all is well now that I understand what is needed.
Tnx for the guidance.
