Show auto update preview can't be switched off if it was on once

[JoeScotty]

Working in Fusion V2.0.20508 x86_64
Have some problems with auto preview (SAUP)/ update preview once (UPO)

So this is the situation after a fresh start:
SAUP was off, I entered values without any break like expected.
Then I clicked on UPO, found no reaction, but it started processing

Tried SAUP and the calculations for the preview started, took 2 min. OK
For changing values I wanted to switch SAUP off.

• after clicking the checkbox the it calculated started again (why?)
• the checkmark did not disappear, so I did not know if the click was registered
• so clicked once again.
• after some recalculations I wanted to change a value from 1,0 to 1.35. Recalc was startet two times after every digit
• Recalc does not start when changing values in the custom profile table.
• Also calling gridfinity in crate windows takes 2 mini. in my case (no checkmark in SAUP!)

Therefore the problem seems to be:
. the SAUP cannot be switched of after it was activated once.

• unchecking the SAUP checkbox should not start another calculation and immediately remove the checkmark
• if SAUP is switched on, it should activate the calculation when clicking another field, not after each digit.
• if SAUP is off and click on UPO, this seems to activate SAUP

Stopping and restarting the AddIn in fusion solves the problem until the next time checking SAUP.

The Gridfinity AddIn is a very helpful extension, but it is hardly usable currently.
Please take a look into this behaviour.
Thanks!

Digging a bit deeper in the sourcecode I found a way which helps a bit:
The Show Auto Preview Checkbox is kind of disabled now.
The old manual preview button is a checkbox now, which works like the auto preview should work.
You can switch the preview on, then it updates the preview at every changed digit.
And you can switch preview off, the preview disappears and you can change several parameters without having to wait for preview calculation.
It is not a complete bugfix, but it helps to be able to work again.
If somebody is interested, I could prepare a documentation of changes.
