now I'm getting the spinning menu and it closes...
Please check if this is fixed by restarting Couatl from the Traybar icon.
when parked in a spot to small I get "parking spot too small"... it totally unable to use... uninstalled several time(won't completely uninstall).
Not sure why you think this is any different than P3D or it's even an issue. In fact, quoting from the the GSX manual, Page 11:
Note for existing GSX users
GSX will warn you if a parking spot is either “too small for your aircraft”, or is already taken by an AI. However, a big change from previous versions is that will allow you to use it anyway
So, not only the way GSX checked the parking radius against your airplane Wingspan is IDENTICAL to P3D, but in MSFS you can even use the parking anyway, when in P3D you had to customize some options, because it would have prevented you to use it otherwise.
Of course, the other ways to customize this are still available, both on a global basis, quoting from the GSX manual, Page 27:
Ignore Wingspan when parking
This option will disable the “Parking Too Small” warning. Note that, with this version, GSX will always allow to use a parking, even if it says it’s too small but, with this option, you can also disable the warning.
But also on the airport level customization, quoting from the GSX manual, Page 33:
Max Allowed Wingspan
This option allows to override the parking radius in the airport .BGL, used to verify if a parking is too small to fit a certain parking. Sometimes, it’s possible a scenery has actual space available around a parking spot, but the scenery designer has specified a smaller radius for that parking spot, maybe for AI flow reasons, or to fix problems with default ground vehicles, or simply because of an oversight.
