I've done something that has disabled the selection of the OpPoints for a Polar, and the Display and Graph Curve settings are also disabled, as per attached image.
Although I've looked at every menu item that I can find, and did Options > Restore and > Reset, I'm still unable to view opPoints. The program is working and I can export the Polars OK.
I can also open a previous project, and select/view the OpPoints.
But if I create a New Project and import the foils from the problem Project, it too has the OpPoint selector etc disabled.
Advice on how to fix whatever I've done would be very much appreciated!
I'm still trying to determine what the issue is. I'm testing an Eppfler 376 foil, and when I first began trying it, everything worked AOK. I have another Project using a different foil which is still OK.
I tried starting a New Project and loading the foil, and ran it "as is" without Normalising or doing Refine Locally, and left panels at the original 61. No go.
Then I tried doing the Normalising & Refining, setting the Panels to 100 as recommended. I did notice that it did not save panel number at 99 as it does with my previous foils... something to do with a closed TE? I don't know how to check that. But again, no go.
I also made a copy of the previous project that works, loaded the Eppfler foil, and tried it - same result! The other foils displayed the OpPoints and Display options, the Eppfler one does not. :(
Any chance you could try out the Eppfler foil I attached above, and see if XFLR5 works OK for you pls? Wondering if I should try a re-install next...
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Somehow, the issue seems to be related to the foil itself, but I'm stumped. I have attached the foil dat file, which I got from http://airfoiltools.com/airfoil/details?airfoil=e376-il - I used the Selig format dat file.

Hello Max,
.... you have to set the checkbox "Store Opp" to see the Op Points ...

Thanks Jochen, but it is checked.

Hi Max,
in the hardcopy in your first post the checkbox was not selected. That's why I meant ...
I tried it and it worked normal . Mmhh -

Sheesh! I feel like such an idiot... I thought you were referring to Options > Prefs > Save...
And all the time it was right in front of my face, after many hours trying everything I could think of.
Thanks for your patience, you just made my day!
Cheers, Max
