Knime 2.10.0 Crashes while saving

Hi Guys, 

I have recently downloaded and installed knime (i just download the file and then unzip it into my local drive)

Everytime I try to save a workflow knime just "hangs". If I try to run and save the same workflow in version 2.9.1 there are no problems.

Does anyone have any ideas?

 

Cheers

This is the last part of the log file

Hi Andy, 

We are becoming aware that there is likely a bug in the new auto-save feature that needs squashing.  Have a look here:

http://tech.knime.org/forum/knime-users/auto-save-bugs

Next time KNIME freezes, if you can extract a stacktrace, this will help us identify the cause of the problem. 

Sorry for the trouble.
