HI,
Just notifying this as a solution if someone else has the same problem.
By no apparent reason, the columns of IAC page on .ioc configuration editor running on CubeIDE become uselessly narrow (see image below). Restart the IDE did not help. Other pages show normally. In CubeMX this does not happen.
The solution is to move the separator bar between the project hierarchy panel and editor panel to left. Apparently the IAC page does not handle the width scaling correctly (other pages on that tab do that nicely).
Cheers, heke
