Crash Upon Opening Second Instance

[gwport]

GW 2.3.43.

When opening a second instance of GW (IIRC, rarely also when starting GW as a first instance), GW creates a Java language error log window that needs to be closed before one can proceed with using GW (but GW as a whole does not crash entirely). Afterwards working appears to be normal. IOW, there seems to be at least one bug in an initialization or a garbage collection routine. Unfortunaly, I cannot give more precise error details yet. If you wish, I will wait for the next occurrence and try to copy and paste the error log.

It would be good to get screenshot (or text) of error message.

GW was not open (I did not check if it was still running as a process). Then I double click on an SGF and get this log. When closing GW and then double clicking on the same SGF again, GW starts normal without any error log.

These two problems are due to same bug.
I will create corrected installation package later today.

After some usage of the corrected GW version, it appears that indeed the bug has been fixed, thank you! Just curious: What kind of bug was it?

[lpaatero]

Nothing interesting there
One method dealing with finding first free label in node was not handling null value.
