[quote=Marco Kalter]Can you let me know the exact symptoms? [/quote]
I open an SQL file click F8 to run, then open another window/file and do the same. The PL/SQL Title Bar then displays (Not Responding) I cannot tab between the two windows and the timer stops incrementing.
Therefore, I don't know if the script is still running or if I should abort the program and start again. Wherupon I am likely to meet the same scenario.
Any help is appreciated.
