Created attachment 157770 [details] UK IHT 400 form SUMMARY In the UK form IHT 400 (included) there are many many tick boxes; most of them work fine, except 44 and 45, which instead change boxes 48a and 48b. https://www.gov.uk/government/publications/inheritance-tax-inheritance-tax-account-iht400 STEPS TO REPRODUCE 1. Click on the No/Yes boxes for 44 or 45 on page 6 OBSERVED RESULT The ticks appear in boxes 48a and 48b EXPECTED RESULT The ticks appear in the box you tick SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
This *might* be a form bug; it's pretty consistent across Okular, evince and Chromium. (Chromium is slightly different, it gives the tick boxes a default of No which makes it easier to avoid)
Given that this is what Adobe Reader does too, it's either a form bug or how it has to behave. Closing the bug.
Yeh, not too sure what's going on here. 44 and 45 look like all the others to me in the raw PDF - although I can't say I fully understand the syntax yet; they both have an '/Off' and '/Yes' in the /N and /D sections. 48a and 48b (objects 2416/2417) both do it differently with the buttons in children, and have 4 children, two 'No/Off' pairs and two 'Off/Yes' pairs - which doesn't make any sense to me since they only seem to have tow buttons each.
