Hi,
Do you mean when you have tables stacked the active table is not coming to the front? If so have you ticked Table in foreground or table under the mouse option?
I am unable to reproduce the Table Ninja tile issue can you please make sure you have Aero windows theme on and Turn off UAC.
Also we have released a version yesterday with some fixes can you please make sure you have this update to check for the latest update go to the updates tab > check for updates. Then if this did not resolve it continue with sending us the log files as suggested below.
Go to the settings tab in TN2 > click on send logs to Table Ninja
Once you do this it will create a zipped file with all the settings/logs, Please note the location the files are being saved to.
Once you do this attach the zipped file to an email and send it to us so we can review it for any errors.
