137_RC3 can't delete a session in Data Manager

Can you save your sessions and attach the xml file here so I can analyze it ?

You can also attach user/log from the day when it happened.

Here is the log attached (at around 17:30). As you will see I could not save the session. 

But the names of the sessions are : 

18h_17h NY (NYMEX, COMEX, ICE US)) 

with blanck spaces (which is a problem I suppose)

or 

18h_17h NYGlobex (NYMEX, COMEX) 

I made a small video. If you need it I will upload it somewhere.

Have a nice day !

Can you please attach file data.db from \user\data ??? Sessions are stored in this db file, I will check what is wrong exactly.

I added them by typing it. The 2nd one may come from cloning the previous one. 

If I remember well, there may be a message saying that something is wrong but it creates it anyway. But I am not sure anymore.

When deleting multiple sessions at the same time they are separated by a comma char.

Session name cannot contain any special character ( comma is a special character). 

Please download the latest build of SQX and define the sessions from scratch with correct names.
