Possible bug in 2.5.7

Been having this intermittant problem with Spark 2.5.7 on multiple Win XP clients. You open up the chat window with a user and start typing, press ENTER, and the cursor just moves to the start of the line. The chat window does not get updated, but the message is sent to the other user. Here is the Java exception from the log.

i’ve seent his issue as well.

I have had this issue with one user as well. Uninstalling the software and reinstalling had no effect. However a clean install of the OS on the client machine has cured the issue.

This sounds like what i ran into using 2.5.8beta as well:
