GAMS: log file problems

When running a large NLP in the GAMS/IDE with the new 23.1 version, I noticed that the log from KNITRO is buffered. This is not ideal: a log line should appear right away. Also the log from XA is completely disappeared since a few versions. In both cases the result is staring at a blank window when the job is running. The log is really the user-interface for a solver, so it would be good if a little bit more care is devoted to this.
