Yes something _has_ changed.
https://github.com/livecode/livecode/pull/5456
The issue is really in GLX and can be fixed two ways:
Code your stack to handle all the GLX managed window messages or change the GLX
ThrowError front script handler to something like this:
private command ThrowError pError
## used to throw errors that are not the result of ViewInitialize,
viewOpen, etc. not being in the message path
if pError is empty or \
(item 1 of line 1 of pError is 573 and \
(the number of lines of pError is 1 or \
(the number of lines of pError is 2 and \
item 1 of line 2 of pError is 241))) then
exit ThrowError
end if
throw pError
end ThrowError
There’s probably more robust patches involving checking the handler name in
item 4 of line 1 of the error string against the handler that was sent and not
handled but the above should at least get people out of hot water.
