Frequently have to kill and re-open PL/SQL Developer

[dgs!]

I work remotely and have to VPN into two separate systems throughout the day. When I return to a VPN session where PL/SQL is running, the application remains in NOT RESPONDING mode. Sometimes it comes back to life, sometimes I am offered an option to restart PL/SQL Developer but other times my only option is to close and restart it.

Can you go to Preferences > Oracle / Connection and enable the "Check connection" option?

If this does not help, then to obtain some more diagnostic information, can you modify the shortcut and add the DebugSQL parameter? For example:

"C:\Program Files\PLSQL Developer 12\plsqldev.exe" DebugSQL

Reproduce the problem and send me the debug.txt file that is generated in the %APPDATA%\PLSQL Developer 12 directory (e.g. C:\Users\\AppData\Roaming\PLSQL Developer 12).
