I upgraded from 23.1.1.345.2114 to 24.3.0.284.2209.
It seems that in the latter, the panel inside the Query Result tab is not scrollable when it contains a message like an error instead of a query result grid.
Look at this example, there is no scrollbar (and it's also not scrollable using the mouse wheel).
This is forcing me to vertically resize the Query Result tab the to read the full message (usually the “error at line…” is at the bottom).
Once resized, it can't be rezised again to shrink it and give back space to the Worksheet tab; the only option is to close it.
